Emoji Style Generalization 2

Let me make sure I understand what we're working with here — the emoji-template project from the previous session where we shipped the emoji package and UI toolkit, and now you're shifting focus to "Emoji Style Generalization" by examining the reference projects in the reference folder to understand the broader design patterns across different emoji implementations.

My approach is to first map out what's actually available in those reference projects, then compile a comprehensive inventory of the juice, UI systems, and audio assets across all of them. From there, I'll design a small gameplay slice — something like "super emoji invaders" — that exercises all the core systems the template provides, rather than building a full game. I'm ready to present my understanding and plan before diving into the actual research, and I can ask clarifying questions if needed. to understand the current state of the template. I'll do a quick scouting run: listing the reference folder in emoji-ball-battles, checking D:/ for other emoji projects, and reading the CLAUDE.md file in emoji-template to get oriented. Then I can present my understanding and plan with any open questions batched together.

10  Trivial changes (single-line tweaks, renames, typos, user-specified

I should first confirm my understanding of the task and outline my approach before diving into the actual research. Let me quickly orient myself by checking the archives folder structure and locating emoji-aimer, then I'll present back what I understand needs to be done and how I plan to tackle it.

I'm checking where Emoji Aimer is located and what's in the archives folder, then I'll explain my understanding and next steps.

I'm checking the E:\a327ex directory for emoji-related folders, but the wildcard filter didn't catch anything even though emoji-template exists there. Let me just list out all the directories to see what's actually present.

The filter approach didn't work out, but I've got the list of emoji-related projects on the E: drive now. There's emoji-aimer, emoji-ball-battles with its reference folder containing several other emoji projects, emoji-ball-bounce, emoji-ball-battles-generated, and emoji-template which is what I'm targeting. I'm also checking the D: drive.

D: has dated archives from 2020 onwards—2020-2021 code, 2022 code, 2022-2023 code, 2023 code—which should contain older emoji-like games from that era. Before I dive into the actual research, I'm laying out my understanding and approach: I need to comprehensively catalog all the juice, UI, sounds, effects, and feel elements across the emoji-style games in the reference folder and any other emoji projects I find in those archived directories.

The goal isn't documentation for its own sake—it's to inform how I generalize the toolkit. Then I'll build a small showcase game, likely a Super Emoji Invaders slice, that demonstrates every generalized feature tastefully. I'm also free to discard or replace implementations from earlier versions if the research shows the actual games did things differently.

My plan breaks into two phases: first, I'll sweep through D: to find all candidate emoji projects and get a sense of their size; then I'll read through each codebase (usually single-file Lua) and catalog the juice, UI, sounds, effects, and feel mechanics for each one.

I should also check the existing documentation I've already compiled—emoji_effects_documentation.md and sound_mapping.md—and build on that rather than starting fresh. Given the scale, I'll use parallel agents to speed up the per-game cataloging.

Once the agents finish their passes, I'll synthesize everything into a master reference document organized by category (juice, effects, UI, sound, visual style, environmental details), noting parameter variations across games and suggesting generalized forms. I'll deliver the full analysis in chat too.

Then I need to audit what's already in the emoji-template toolkit versus what's missing, and flag any places where the current implementation contradicts what the research shows—those are candidates for replacement.

Finally, I'll verify whether super-emoji-invaders is the best showcase candidate by checking its coverage, then design a gameplay slice to iterate on.

I'm also thinking through the working constraints: design brief before code, one increment at a time, user testing between steps. There's an important distinction too—the template ships without sounds by design, but the showcase game is a fork, so it can include sounds; that's actually where sound conventions get tested and validated.

Now I'm wrestling with where the showcase game should live: fork emoji-template into a sibling folder to test the fork workflow itself, or build it inside the template as a demo scene? Forking keeps the template clean, but the roadmap mentions the scaffold split isn't finalized yet, so I need to think through the implications.

Actually, building the slice inside emoji-template as main.lua makes more sense—it aligns with the existing roadmap where the demo becomes the showcase, and the slice serves as the template's test harness. Changes can flow back naturally as the toolkit stabilizes.

There's a question about sounds though: the toolkit ships without them, but the showcase will presumably want full audio to test all the juice and UI effects. If the showcase lives in main.lua inside the template, sounds would enter the template repo's assets even though the emoji toolkit itself stays soundless—I should confirm how to handle that split.

For the D:/ sweep, I'm planning to search for emoji-related projects by name within the code folders from 2019 through 2023, but I should verify that's the right scope and ask if there are any specific project names I should be hunting for.

I'll also incorporate the existing research docs like emoji_effects_documentation.md and sound_mapping.md rather than redoing that work, and deliver the full catalog analysis in chat since logs get published anyway.

For the research itself, I'm thinking I should propose using parallel Explore agents to fan out across each game and build per-game catalogs, then synthesize the results — the user hasn't explicitly opted into Workflow orchestration, but Agent tool use is fine for this. I should also flag that some assets like the hitfx defaults came from EBB/Aimer already, but invented elements like miss-feedback and damage numbers will need correction based on what the research uncovers.

One thing I need to clarify: the user mentioned both Emoji Ball Bounce and Battles, and they're separate projects. I should quickly check if both have reference folders to make sure I'm pointing to the right sources in my plan.

I'm checking whether the emoji-ball-bounce folder has its own reference directory, since the user mentioned reference folders for that project.

I'm organizing my approach: first I'll lay out what I understand the task to be and the corpus I'm working with, then map out my research phases using subagents to fan out the work, synthesize everything into a catalog document, and deliver it through chat. I'll also do a gap analysis against the current template and showcase some examples to ground the work.

The user confirmed that showcase is in emoji-template as main.lua, and for sounds I need to research whether there's enough commonality across games to include them in the template. Importantly, I'm starting fresh with research and not referencing any previous documentation. Now I'm moving into Phase A to sweep the D:/ directory and create an inventory, followed by Phase B for fan research.

I'm starting with a D:/ sweep to identify emoji-related projects from the 2020-24 era, checking for both "emoji" and "super" in directory names, and I'll also need to deduplicate reference folders across the different games before fanning out agents with a strict rubric that excludes the old research docs.

Running a PowerShell search across the code folders...

Once I have the project list, I'll spin up parallel Explore agents to catalog each game systematically—documenting the path, engine type, file structure, player mechanics, and visual juice elements like springs and flash effects.

For each game, I need to capture the full effects pipeline: squash/shake/slowtime/hitstop and zoom tweens with their parameter values and trigger points, plus particle systems, hit effects, trails, and environmental details like clouds and wind. I'll also inventory the UI layer—screens, widgets, HUD styling with colors and fonts—and map out the sound system including all audio assets, trigger-to-sound connections, and any pitch/volume variation patterns. Style constants like resolution, outline/shadow techniques, palette, fonts, and cursor behavior round out the catalog. I'm explicitly avoiding the old reference docs from prior research and pulling everything directly from source code and assets.

I need to catalog three games: emoji-ball-battles, emoji-ball-bounce, and emoji-aimer, while deduplicating versions like "super emoji box" versus "super-emoji-box" and handling reference copies across projects—I can do a quick hash diff on the file trees myself rather than spinning up multiple agents. Each game's main.lua might be large, but that's manageable for a single agent per game.

I'm planning to run about nine to ten agents in parallel batches: the two super-emoji variants, the pop game variants, super-emoji-pairs, emojunky-one, emoji-merge-main, emoji-aimer with its reference folder inventory, emoji-ball-battles, emoji-ball-bounce, and any new finds from the D:/ sweep. Before I fan out to all these agents, I should do the D:/ sweep and deduplication first, then start the sweep now. I'll also skip reading the old docs myself to keep the workload focused.

I've already seen some context from emoji-template's CLAUDE.md that references things like the fx.lua header and emoji_effects_documentation.md, which is unavoidable. Since the user's sound decision depends on commonality, I need to capture complete sound inventories with filenames and trigger locations across all games so I can cross-compare them. Better yet, I'll hash all the .ogg and .wav files across every project's assets using PowerShell to find exact duplicates—that's an objective measure I can run myself as part of Phase A/C.

My plan is straightforward: first sweep D:/ and list emoji-aimer references, then deduplicate those references by comparing file tree hashes and building a sound-file hash matrix to establish ground truth on shared sounds. After that I'll fan out to the agents and synthesize findings. This research phase is autonomous work—I'll do it fully and return with the complete catalog.

I'm aiming to deliver phases A through D in one turn: the catalog, gap analysis, sound commonality verdict, and invaders coverage verdict. That gives us everything needed before moving to phase E, which requires design iteration with you.

Starting now with the D:/ sweep.

I'm digging through the 2022-2023 code folder and finding a bunch of emoji-related projects that aren't in the reference directories. There's an emoji sounds project that could be really useful for the sound question, plus several other emoji variants like emojia-lore, emojian, and emojunky-one, though some appear to be duplicates or experimental attempts.

I should also check inside the 2023 code folders and the emoji sounds directory specifically to see what else is there, and I'm noticing that the reference folder has "super emoji box" and "super emoji pop" with spaces — those might be the built versions compared to the dash-separated source folders I'm finding. I'll set up a quick task list to systematically go through the 2023 code directories, examine the emoji sounds folder contents, and check which of these new emoji projects have main.lua files and what their sizes are.

I found a folder with about a dozen unreleased emoji projects that look relevant to your question, including some directly related to emoji sounds. Let me dig deeper into these files.

I'm finding more emoji projects scattered across the directories—emoji-merge, super-emoji-draft, and super-emoji-lanes in the main code folder, plus several super-emoji variants in code_old like ball, box, and invaders. Since many of these don't have a top-level main.lua, I need to check their actual file structures to understand what I'm working with before passing them to agents.

Looking at the project structure across these game projects, I'm noticing a pattern in how they're organized — the older LÖVE2D games use a src/ folder structure that suggests they came from a common engine template, while the newer ones like emoji-merge switched to an Anchor-based setup with much larger main files, and super-emoji-lanes appears to be Anchor-based but with just a stub main file.

I should check the actual size of the src/ folders in a few of these projects and compare them against the reference copies on the external drive to see if they're duplicates or if there are meaningful differences between the versions.

I've identified the src/ projects as LÖVE-era games, with emoji-merge being the most substantial at 86KB, while the others are stubs or design docs. Now I'm comparing the E:\ reference copies and sizing the src/ games.

Looking at the codebase sizes, super-emoji-invaders stands out as the largest with an 81KB main.lua file, which aligns with what you suspected about it being the most complete implementation. I'm also noticing that emoji-merge appears twice in slightly different locations with nearly identical file sizes (85KB and 84KB), so I'll need to compare them to see what's different. The emojunky-one project has a more distributed structure across multiple files, with aika.lua at 45KB being the largest component. There's also a shared sound bank folder from 2022-2023 that likely contains assets used across multiple games, so I need to compare those against each game's audio files. I'm also identifying several duplicate projects across different directories that need deduplication — multiple versions of invaders, emoji-merge, pairs, pop-prototype, emojunky-one, and the box variants scattered across reference folders and the main drive.

My approach is to hash the main.lua files across all projects to quickly identify duplicates, then build a comprehensive sound asset matrix by collecting and hashing all audio files across every project and the shared sound folder to determine what's actually being reused. Once I have that data, I can create a task list and distribute the work to agents.

I found that super-emoji-invaders has an 81KB main.lua and appears to be the most complete version. Now I'm deduping the D:\ versions against reference copies by file hash and sizing the remaining first-party games.

I'm going through the deduplication results for these emoji projects. Super-emoji-invaders has nearly identical versions with just a 2-byte difference, so that's fine. Emoji-merge has a newer version in D:\ that I should use, but I'll check what changed. Emojunky-one's reference version is larger and likely newer, so I'll go with that. Still reviewing the rest of the files.

Now I'm organizing the definitive corpus by tier. The major games are super-emoji-invaders (81KB LÖVE engine), emoji-merge (86KB Anchor v1), emoji-aimer (246KB), emoji-ball-battles (259KB), and emojunky-one (multi-file platformer). These are the core titles I need to deep-read.

For tier 2, I'm cataloging the smaller prototypes like super-emoji-box with its modular structure (plants.lua, particles.lua, and other systems), super-emoji-pairs, and super-emoji-pop, though I still need to verify exact file sizes for some of these. I should skip the stub files and design docs, then map out the sound assets from the shared folder and the commercial SFX bundle for provenance. For the agent fan-out, I need to give each one the rubric while blocking access to the generated analysis documents in the reference folder—though the developers' own todo notes embedded in the game files are fair game. B through G are the remaining game projects — emoji-aimer is the largest at 246KB so I'll keep it as one agent, emoji-ball-battles at 259KB gets its own agent, emoji-merge has a newer D:\ version to track, emojunky-one spans multiple files around 165KB total, and the two "super emoji box" variants plus "super emoji pop" versions each get consolidated agents to compare their evolution.

For the smaller titles like super-emoji-connect, guncraft, emojian, and the ball variants, I'm grouping them into two agents to keep things manageable. The sound matrix is its own challenge — I'll hash the audio files myself using PowerShell, then have each game agent report back their trigger mappings, plus verify what's in the Ultimate SFX Bundle folder. That brings me to roughly ten agents total.

These are all read-only Explore agents using the standard toolset minus any editing capabilities. For the rubric, each game gets the same template: I document the path, engine type, era, and whether it's a prototype or shipped product with a full file breakdown. Then I catalog the player verbs for the mechanics matrix, list every juice effect with its trigger conditions and parameter values pinpointed to specific lines of code, and do the same for particle and visual effects.

I also need to inventory all UI screens, HUD elements, and their animations, map every sound asset to its trigger with exact pitch and volume ranges, extract all the style constants like resolution and palette values, and flag any distinctive feel tricks that could be generalized. I'm avoiding reading from that restricted directory.

For the output, I'll use markdown with exact file references and values to make this a complete, exhaustive catalog. I'm debating whether to set up formal task tracking for this multi-phase effort — it would help me keep 10 agents organized, but since results come back automatically, I'll skip the overhead and just move forward with the phases I've already mapped out.

Before spinning up agents, I'm going to build a sound hash matrix myself since it's objective data I need in the final synthesis anyway. I'll scan all the sound files across the projects' asset folders and the shared emoji sounds bank, hash them to find duplicates, and group by both hash and filename to catch re-encodes that might differ in hash but share names. Let me write a PowerShell script to collect and analyze the sounds from the key directories. I'll write the results to a CSV file for analysis, then launch the agents in parallel while I hash the sound files in the background—they're complementary tasks rather than duplicates. Before starting, I need to draft the shared rubric text and set up the agents with the default Explore type, which is appropriate for reading through these large codebases, though I'll keep in mind that Explore agents locate code rather than deeply review it.

Actually, general-purpose agents might be better here since I want full-file reads for a thorough catalog rather than just excerpts. I'll use 10 general-purpose agents, each handling 20-260KB of Lua code, with a common rubric that I'll vary per agent based on their target list. One more thing—I should have the agents flag engine-level juice helpers too, since the engine folders contain implementations like Spring classes and shake effects that matter for understanding how the juice generalizes across games.

I also need to make sure agents check the assets folders: cataloging sound files, noting spritesheets, and examining shaders in detail since shader differences (outline thickness, offsets, constants) affect the pipeline across games. Now I'm ready to write the prompts with a common preamble and per-agent targets, then launch all 9 agents at once since they'll run in the background. I'm cataloging the remaining projects — the emojunky reference version with its multi-file structure, the box and pop variants with their naming conventions, and several smaller ball-themed games scattered across different drives. Once I gather these structured catalogs from each agent, I'll synthesize them together while running sound hashing in parallel. I need to establish a common rubric for the prompts and make sure each agent understands they're building toward a generalizable template.

The key constraints: agents should focus on mechanics-agnostic feel elements, exact parameter values, and implementation details. They must skip any .md files at the root of the reference directories since those are polluted AI analysis docs, but they can read developer notes inside the game folders. Everything is read-only, and I'll ask them to include file:line references so I can verify their claims later. Now I'm drafting the prompts with a shared core of about 500 words plus game-specific details.

The agents are all running now, so I'm going to build the sound hash matrix myself while they work. I need to gather all the audio files from across several directories—emoji sounds folders, asset directories from various emoji game projects, and some 2023 files—to compile them into the matrix.

I'm writing a script that will recursively search through each project directory for audio files, skip any build or binary folders, and output a CSV with the project name, filename, hash, and file size for each sound. Then I'll analyze the results by grouping them by hash to identify duplicates.

I've got 9 research agents running in the background while I build the objective sound-commonality data by hashing every sound file across projects to identify exact duplicates shared between games.

total sound files: 506

emoji-ball-battles: 70

super emoji box: 65

emoji-sounds-bank: 57

super-emoji-pairs: 57

super-emoji-invaders: 53

super-emoji-box: 24

emojunky-one: 21

emojian: 21

super-emoji-ball-old: 21

super-emoji-guncraft: 21

super-emoji-pop-proto: 17

super-emoji-stack: 17

super-emoji-mix: 17

emoji-merge: 15

super-emoji-ball: 9

super-emoji-connect: 9

emoji-ball-bounce: 7

super emoji pop: 5

I found 506 sound files total, but emoji-aimer shows zero results even though it has an assets folder—the sounds might be nested in a subdirectory like assets\sounds, or they could use a different file extension. Let me investigate where aimer's audio files are actually stored.

Also noticing "super emoji pop" only has 5 sounds. Now I need to group these files by hash across all projects to identify which sounds are shared between them.

I've hashed 506 sound files, but emoji-aimer is showing zero results which seems off—now I'll locate its actual sound files and run the cross-project duplicate analysis.

---

I'm checking what's actually in the emoji-aimer assets directory and how the main.lua file loads them, since the earlier directory listing showed the assets folder exists but I haven't confirmed whether it contains any sound files or is completely empty.

Interesting—emoji-aimer is completely silent, no audio files at all despite having the richest UI of the bunch. I should verify whether the code even contains sound effect calls or if they were never implemented. Now I'm moving into the cross-project duplicate analysis using the CSV data.

I've confirmed that emoji-aimer contains no sound assets—just 58 PNG and font files. Now I'll analyze the duplicates.

distinct sound files (by hash): 161

hashes appearing in 2+ projects: 62

So there's a clear pattern here: out of 161 total sounds, 62 are shared across multiple projects, with a core set of about 50 sounds appearing in up to 13 different projects. These shared sounds cover the essentials—enemy interactions, weapon fire, movement impacts, collectibles, player feedback, and environmental effects—which confirms that sound reuse is definitely a significant part of the design.

The emoji sounds folder on D:\ is essentially the canonical library, and nearly all of those 57 files show up across the games. What's interesting is how the same audio file gets repurposed with different names depending on the game's context—the same hash might be labeled enemy_die2 in one game but saw_hit2 in another, or land_impact becomes ball_wall. It's the same asset serving different semantic roles.

Looking at the cluster structure, there are two distinct eras: an earlier "action era" cluster with games like box, emojian, guncraft, and invaders that share grass, land, hop, revolver, and coin sounds, and a later "pop/stack/mix era" cluster that emphasizes spawn, pop, teleport, cloud, and UI family sounds. The newest and largest games—super emoji box, invaders, and pairs—essentially have the union of both, while the puzzle-focused games like super-emoji-connect and super-emoji-ball share their own distinct UI-centric set with click, hover, error, success, and finish sounds.

Now I'm noticing that emoji-merge's 15 sounds don't appear in any of the shared groups at all, and emojunky-one's 21 sounds are similarly isolated—they're completely unique to those games. Meanwhile, emoji-ball-bounce pulls from the EBB set with revolver_shot, land_impact, and concrete sounds. The "Ultimate SFX Bundle (2020)" on the drive is likely where all this originated. I should pull the unique sound lists for emoji-merge and emojunky to understand what makes them distinct, then cross-reference with the full canonical bank to complete the sound picture before moving into trigger mappings from the agents.

I'm also going to check for files with identical names but different hashes across projects—like ui_hover appearing with multiple versions—since the bank's version should be the authoritative one. Once I run those two queries, I can wait for the agents to finish.

I've found the canonical shared sound bank — a folder on D:\ with 57 files used across up to 13 projects, though files get re-aliased per game and two games sit outside the bank entirely. Now I'll examine those outlier games and investigate the cases where files share names but have different hashes.

So there's a canonical sound bank in that 2022-2023 folder with 57 curated files that served as the shared vocabulary for the family's games from that era, but emoji-merge pulled in a completely different set of Japanese free sound effects with their own naming conventions and aesthetic.

The earlier emojunky-one game predates the bank entirely and used freesound attribution tracks with its own platformer-specific sounds, while emoji-aimer has no sound files at all. The answer to whether there are strong commonalities is yes—the bank covers combat, movement, economy, UI, and structural sounds across roughly ten games—but the aesthetic divergence is real too, especially with merge's deliberate cute Japanese palette. The bank would be a legitimate template foundation, though it wouldn't capture every game's specific direction.

I'm checking the provenance of this sound bank against the Ultimate SFX Bundle from 2020, which is likely where it was curated from. The licensing matters here—the bundle permits use in games, but redistributing it as an asset pack in a public template repo would be problematic. I should hash-match a sample of the bank files against the bundle to confirm the source, then flag the licensing implications to the user before deciding whether to ship the sounds with the template.

I've mapped out the sound architecture: a 57-file emoji sounds folder serves as the shared vocabulary across the 2022–23 family, while three games use separate assets or silence. Now I'm checking whether the core bank was curated from a commercial bundle to determine if it can be redistributed in the template repo.

I've got about 9000 files to work with, which would take a while to hash completely, but I can be strategic and focus on the major sound library folders instead of processing everything.

Actually, there's a fundamental problem here: the bank files are in .ogg format while the bundle likely contains .wav files. If the developer converted between formats, hash matching becomes impossible — the same audio content would produce completely different hashes. I should check what file extensions are actually in the bundle first to see if hash comparison is even viable. If not, I'll need to pivot to filename matching instead, searching for distinctive names like "revolver," "dagger," "grass," or "hop" to establish provenance that way.

.wav: 9022

.DS_Store: 28

.ogg: 1

---name probes---

*revolver* -> Cock Revolver_01.wav | Cock Revolver_2.wav | Revolver Reload_01.wav | Revolver Shot_01.wav

*dagger* -> Dagger.wav | Crafting Dagger 1.wav | Crafting Dagger 2.wav | Dagger Impacts Shield 1.wav

*grass* -> Grass 1.wav | Grass 2.wav | Grass 3.wav | Grass 4.wav

The sound files in the bank are clearly sourced from the Ultimate SFX Bundle—revolver shots, dagger impacts, grass rustles, coin clinks—which means they're commercial assets that are fine for shipping in games but shouldn't be redistributed in a public template repo since that violates the pack's licensing terms.

Now I'm waiting for the agents to finish analyzing the larger files, which will take a few minutes. Before they report back, I should document the sound findings I've gathered so far in a scratchpad note to preserve the analysis for the synthesis document.

I've confirmed the audio files are from the Ultimate SFX Bundle and noted the licensing consideration for potential public distribution. Now I'll wait for the research agents to complete their analysis.

File created successfully at: C:\Users\adn\AppData\Local\Temp\claude\E--a327ex\a348cf7a-e979-478b-a7c8-af2429a3d98f\scratchpad\sound_findings.md (file state is current in your context — no need to Read it back)

I've banked the sound findings and now I'm waiting on nine agents to complete their work. There's nothing else I should do that wouldn't duplicate their efforts, so I'll wrap up this segment and let the harness reinvoke me once they finish. I should give the user a quick status update while I'm at it.

Actually, I could use this downtime productively by reading through the emoji-template's Lua files — juice.lua and fx.lua — to inventory what's currently implemented. The CLAUDE.md summary is helpful, but for the gap analysis in Phase D I'll need exact details on what's actually there versus what's missing. Reading those files now while waiting is worthwhile prep work that won't duplicate anything the agents are doing.

I've saved the sound data and now I'm inventorying the template's current juice and effects implementations to establish the baseline for the gap analysis.

2     emoji/juice.lua — the cross-cutting feel conventions of the emoji games.
3   
4     Four pieces:
5   
6     1. hitfx — the spring + white-flash pair every interactive entity carries.
7        hitfx_init(e) attaches the standard springs ('hit' uniform pop,
8        'squash_x'/'squash_y' directional deform) to an entity that already has
9        a .timer (timer_new) — it creates e.spring if absent and e.flashing.
10       hitfx_hit(e, pull, flash_duration) is the standard "I got hit" reaction.
11       Draw side: scale by e.spring.hit.x and pass
12       `e.flashing and white()` as layer_image's flash arg.
13  
14    2. hitfx_squash — directional wall-impact deformation (from
15       emoji-ball-bounce / EBB): squash perpendicular to the wall, stretch
16       along it, with the opposite axis pulled at HALF magnitude for a
17       teardrop-ish flatten. wall_hit_intensity(speed) is EBB's intensity
18       curve (linear 0..800 speed, cubic_in_out below the midpoint,
19       circ_in above).
20  
21    3. slow_mo — micro slow-motion for impact moments. slow_time(scale,
22       restore_duration) dips the engine time_scale instantly and tweens it
23       back to 1 (cubic_out). The host calls juice_update(dt) at the top of
24       update(); it pushes slow_mo.scale into the engine and returns the
25       SCALED dt the rest of update should use (`local sdt = juice_update(dt)`).
26       The recovery tween itself runs on scaled time, so deep slows naturally
27       stretch their real-time recovery — Emoji Aimer's choice, kept.
28  
29    4. camera_punch — the punch-in zoom that keeps the hit point fixed on
30       screen (the world scales outward from the impact instead of the camera

3     Ported from Emoji Aimer (which ported them from EBB / super-emoji-pop /
4     super-emoji-box). Four classes + spawn wrappers:
5   
6       hit_circle(x, y, args)            — expanding/shrinking ring at an impact
7       hit_effect(x, y, args)            — the 'hit1' white "pow" spritesheet burst
8       hit_particle(x, y, args)          — directional colored streak w/ gravity
9       emoji_particle(x, y, image, args) — flying emoji sprite (stars, sparkles...)
10  
11    Every spawn_* wrapper registers into the global `fxs` list; the host runs
12    `collection_update(fxs, sdt)` in update() and `for _, f in ipairs(fxs) do
13    f:draw() end` in draw(). All draw to `effects_layer` by default (override
14    with args.layer) so they ride the outline + shadow treatment.
15  
16    Common args: flash_on_spawn (true, or a fraction of duration for
17    emoji_particle) makes the effect spawn white then reveal its color —
18    the "flash white, bleed to color" idiom.

I can verify the claims in juice.lua and fx.lua against the agent catalogs to see what's confirmed, contradicted, or missing. I should also inventory the other files like pipeline.lua, sounds.lua, cursor.lua, and transition.lua to understand the full current state.

1    --[[
2     emoji/pipeline.lua — the signature emoji-style render pipeline.
3   
4     The look: every content layer gets a chunky BLACK OUTLINE derived from its
5     own alpha (outline.frag, a 5x5 neighbor sample), composited immediately
6     beneath it, and the world layers cast a shared DROP SHADOW offset (4, 4)
7     down-right (shadow.frag). UI/text drawn in white reads as black-outlined
8     white glyphs for free. This is the pipeline every emoji game hand-rolled
9     (Emoji Ball Battles, Emoji Aimer, emoji-ball-bounce, and the 2022-24
10    engine generations before them) — here it's declarative.
11  
12    Usage (in main.lua, after require('emoji')):
13  
14      emoji_layers({
15        { 'bg' },                                  -- plain: no outline, no shadow
16        { 'game',    outline = true, shadow = true },

18        { 'ui',      outline = true },
19        { 'cursor',  outline = true },
20      })
21  
22    This creates a global `<name>_layer` per entry (bg_layer, game_layer, ...),
23    a derived `<name>_outline` layer per outlined entry, and one shared
24    `emoji_shadow_layer`. Queue draws into the content layers as usual

4     and this draws on its own outlined layer so it reads with the same chunky
5     black halo as everything else, on top of the whole scene.
6   
7     Juice carried:
8       - horizontal sway: mouse stops after fast horizontal motion → rotation
9         spring pull in the motion direction (clamped ±π/4, 0.2s cooldown)
10      - vertical squash: mouse stops after fast vertical motion → brief
11        y-squash tweened back (deeper + longer for faster motion)
12      - click press: main-spring pull 0.5 + tilt π/16 + squash (0.9, 0.7)
13      - click release: main-spring pull 0.25 + tween back
14      - cursor:flash(duration?) — white blink acknowledgement (pickups etc.)
15      - cursor:pulse(force?)    — bare spring pulse (hover acknowledgement)
16  
17    Requirements on the host:
18      - bind('click', 'mouse:1')                (cursor reads the 'click' action)
19      - a 'cursor'-named layer in emoji_layers  (draws to cursor_layer)
20      - spawn_cursor() after emoji_layers; then the_cursor:update(dt) at the
21        END of update() and the_cursor:draw() in draw().
22  
23    The (+7, +9) draw offset and the -π/8 base tilt are the super-emoji-pop
24    calibration that lands the sprite's FINGERTIP on the actual mouse position.

# EMOJI AIMER — Feel Toolkit Catalog

**Corrections to the task brief up front:** (a) This is an **Anchor 2** game, not Anchor v1 — the header comment says so (`main.lua:2`), and the `anchor/` framework is the procedural v2 style (free functions, `spring_new`/`timer_new`/`layer_*`, only `collider` is a class). (b) The game has **NO AUDIO WHATSOEVER** — no sound module exists in `anchor/` (modules: animation, array, camera, class, collider, color, font, helpers, image, init, input, layer, math, memory, object, physics, shake, spring, spritesheet, timer), zero audio assets in `assets/`, zero play calls in main.lua (verified by grep — the only "pitch" hits are grid-pitch variables). (c) "Medals" are not a popup/achievement system — they exist only as the top three **combo-tier colors** plus unused mockup PNGs in `reference/medals/` (bronze/silver/gold/cross_mark/plus). Section 6 below is therefore a negative finding, and section 8 covers what the medal *colors* actually do.

---

## 1. IDENTITY

- **File:** `E:\a327ex\emoji-aimer\main.lua`, 5,746 lines. Engine: Anchor 2 (`require('anchor')({...})`, main.lua:14–20).
- **Resolution:** 480×270 internal, **scale = 3**, **filter = 'rough'** (nearest), title 'Emoji Aimer' (main.lua:14–20). `gw, gh = width, height` (main.lua:22).
- **Completeness:** playable vertical slice mid-iteration. Full round loop (playing → cleared → payout → shop → next round → won/lost), 15-item shop with stacking, familiars, resources/physics. Visible WIP: bow familiar rotation/firing largely commented out behind `DEBUG` blocks (main.lua:1450–1547, 5344–5352), tier strip tiers 3/4 locked, ROUNDS times set to 9999 placeholder (main.lua:129–135), shop described as "scattered gallery … replaces the real shop layout for now" (main.lua:5541–5543).
- **Companion docs:** `design.md` (loop spec: timed rounds, cash-out bet, Balatro interest, combo tier ladder), `ideas.md` (3 scoring ideas), `sap_reference.md` (Super Auto Pets trigger/effect catalog mined for modifier shapes; "Croissant-style cumulative, Pig-style sell-payouts, Honey-style summon-on-miss, Cat-style multipliers, Dragon-style purchase-triggered stacks" flagged as richest archetypes).

---

## 2. VERBS

**Primary verb — click a target** (main.lua:5291–5302): on `input_pressed('click')` in 'playing' (and no transition active), radius-test all targets (`target:contains`, radius 12, not clickable until spawn_scale ≥ 0.5, main.lua:2085–2088); first hit wins; hit point passed as `(mx, my - 1)`. No hit → `on_miss`.

- **Target:** `direct_hit` 🎯 emoji, TARGET_RADIUS = 12, TARGET_HP = 3 (main.lua:62–63). Static Box2D circle collider so resources bounce off it (main.lua:2060–2061).
- **Damage** = `BASE_DAMAGE(1) + item_count('swords')` (main.lua:1986–1988). **Score per hit** = `(1 + meat_bone_count×1 + combo_tier().score_bonus) × (bacon_count + 1)` (main.lua:1974–1981).
- **Miss** (main.lua:2023–2030): Shield charge available → consume silently, keep combo. Otherwise: red miss_x marker at click point (only if a streak existed) + combo break.
- **Combo** (main.lua:69, 2011–2018, 5171–5174): window 1.5 s (+0.5 s per Snowflake stack), refilled on every hit; timer expiry or miss → break to 0.
- **Resource gathering:** kills at tier ≥ 20 roll 25% per HIT for a coin (main.lua:3092–3098); resources are Box2D dynamic bodies pulled to the cursor within PULL_RANGE 110 px with force `PULL_STRENGTH(1000)·t^0.3` (t = 1−dist/range; upward-Y force ×2 against gravity), collected via a hand-hitbox AABB (x 0..10, y 0..13 relative to mouse) (main.lua:95–110, 2886–2951). Arm delay 0.6 s before pull/collect (main.lua:115). Debug spawns: Z/X/C = coin/gem/crown (main.lua:195–197). Values coin/gem/crown = 1/5/25 gold (main.lua:74); coins also grant +5 score on pickup (main.lua:2896–2898).
- **Round structure** (main.lua:129–135, 5259–5271): 5 rounds, score targets 10/20/60/80/120, timer counts down (currently 9999); reach target → **CASH OUT** button appears bottom-right (96×22 at gw−100, gh−26; main.lua:120–123); click → 'cleared' → all resources vacuum to cursor (range-ignoring full-strength pull, main.lua:2881, 2938–2939) → yellow circle wipe → **payout** overlay (CLEARED $10 + TIME BANKED $1/2s + INTEREST $1 per $5 held capped $5; main.lua:5013–5038) → click → shop (or 'won' after round 5). Timer to 0 below target → 'lost', `death_reason = 'TIMER RAN OUT'`.
- **Shop** (main.lua:4694–4747): click tile to buy (all prices $5), stacks are linear levels; hover tooltips; NEXT ROUND button → wipe → next round. 15 items: meat_bone (+1/stack per-hit), bacon (×(n+1) mult), hot_chili (25% chain to n nearest), bone (every 4th kill: chasing bone, 1+2n hops), bow_and_arrow / swords / gun / boomerang (familiars), dagger (every 4th kill arms instakill click), shield (miss-forgiveness charges, recharge per 5 kills), snowflake (+0.5 s combo window), skull (n instakill charges on bone/arrow spawn), hourglass (+5 s timer/stack), direct_hit (every 5th hit +5n), pool_8_ball (+1 ricochet/stack) (main.lua:3582–3791).
- **Target spawning:** density tick every 0.25 s, ideal count ramps 6→12 across round time, min spawn spacing 48 px (4×radius), 20 placement attempts (main.lua:158–162, 4827–4853).
- **Keys:** R = full run reset from any state; F2 debug AABBs; F3/F4 memory tracker (main.lua:190–197).

**Spring model** (`anchor/spring.lua:40–108`): damped spring `a = -k(x−target) − d·v`, `k = (2πf)²`, `d = 4π(1−bounce)f`. `spring_new()` auto-creates 'main' at value 1. `spring_pull` is an impulse: adds `force` directly to x (position), spring oscillates back to target. Reading `spring.name.x` multiplies scales.

**Shake model** (`anchor/shake.lua`): five composable channels — trauma (Perlin noise, intensity = value², linear decay `value −= (amount/duration)·dt`, default amplitude {x 24, y 24, rot 0.2, zoom 0.2}), spring-push (x/y springs at 3 Hz/0.5), random-jitter instances (linear decay, refresh at frequency default 60 Hz), sine, square, and **handcam** (continuous noise: `amp · noise(t·freq)` per axis).

Every spring/flash/shake trigger:

| Trigger | Effect | Params | Cite |

| **Slow-mo** | time_scale dip | instant to `scale`, cubic_out back to 1.0 over `restore_duration`, defensive snap on finish; engine-wide via `set_time_scale`, local dt also scaled (so physics+tweens+particles all slow) | 3064–3080, 5125–5126 |
| Cursor click press | rotate+squash | `spring_pull('main', 0.5)`; tween 0.05 s cubic_in_out to click_r = π/16, sx 0.9, sy 0.7 (named 'click_scale') | 2595–2600 |

| Bow pull (pre-shot) | string tension | pull over last 25% of 2.2 s cooldown via lerp_dt(0.9, 0.5) toward pull 8 / sy 0.9; release `spring_pull('weapon', 0.5)` + 0.2 s elastic_out (DEBUG-disabled currently) | 1516–1548, 1605–1611 |
| Sword thrust | lunge tween | 80 px over 0.5 s quad_out; `spring_pull('weapon', 0.6, 3, 0.7)`; per-target hit `('hit', 0.5, 3, 0.5)` | 1679–1717 |

| Bullet spawn/ricochet | pop+flash | spawn `('hit', 0.3, 3, 0.5)`; ricochet `('hit', 0.5, 3, 0.5)` + white flash 0.1 s | 1093–1094, 1137–1141 |
| Score gain | chip scrub + kick | score_display tween 0.25 s cubic_out (named 'score_tween'); chip y_offset = 3 → 0 over 0.2 s **linear** (named 'score_offset'); bacon mult panel same kick (offset 3, 0.2 s linear) | 1996–2008 |
| Shop buy | gold scrub + kick | gold_display tween 0.3 s cubic_out; chip y_offset = 4 → 0 over 0.25 s linear ("cash register thunk") | 4629–4638 |

| Shop tile hover wobble | per-tile handcam | each tile has its own shake with handcam amp {x 2, y 2, rot 0.05}, freq 1.0, randomized phase (time = random 0..100); scaled by hover_amount | 4401–4408 |
| Buy fail | error shake | frame/banner/emoji all red for 0.3 s; horizontal sinusoid `sin(p·π·8)·(1−p)·5` px (4 oscillations, amp 5, linear decay, 0.3 s) | 3863–3867, 4584–4589 |
| Slot pulse on item proc | `pulse_hud_slot` | `spring_pull('main', 0.4)` on the HUD inventory slot when dagger/skull/bone triggers | 3285–3292 (called 2138, 2161, 2375) |
| Buy success (slot) | pop | `spring_pull(target.spring, 'main', 0.3)` | 4677 |
| Buttons (cash out / new run / next round) hover | pop | `spring_pull('main', 0.08)` + cursor flash; scale applied to panel only, text stays pixel-sharp | 5184–5186, 4736–4738, 4286–4303 |

**Tween easings actually used:** linear (kick returns, transition-in, particle shrink), cubic_out (score/gold scrub, punch-zoom return, slow-mo restore, transition-out, bow recoil), cubic_in (punch-zoom in), cubic_in_out (spawn scale, hit_circle radius, click squash, damage-number shrink, stab return), quad_out (sword thrust, bow pull), **elastic_out** (bowstring release — the one elastic in the game). Full easing library in anchor/math.lua:448–802.

**Named-tween discipline:** every repeatable tween is tagged ('click_scale', 'stab', 'punch_zoom', 'gold_tween', 'score_offset', 'slow_time', …) so re-triggers replace the in-flight tween instead of stacking — this convention appears at ~15 sites and is load-bearing for spam-safe juice.

## 4. FX

**Particle/effect classes:**

- **hit_circle** (main.lua:566–593): filled circle tweening radius→0 over duration (default 12 px / 0.2 s / yellow) cubic_in_out; optional white flash first 0.1 s. Uses: hit ring, resource-collect ring (10 px white 0.2 s, line 2908), shop buy ring (12 px yellow 0.25 s on shop_particle_layer, line 4657).
- **hit_effect** (main.lua:601–627): 'hit1' spritesheet (96×48 file, 5 frames of 0.03 s, once), random rotation, base scale **1.35** × args.s. Normal hit s=1, dagger kill s=1.5.
- **hit_particle** (main.lua:633–676): directional rounded-rect capsule; velocity default random(50,150); w/h default remap(velocity, 0..250 → 4..12 / 2..6); manual gravity accumulation; duration default random(0.25, 0.5); tween velocity+sx+sy→0 **linear**; draw angle follows velocity vector; optional white flash 0.1 s.
- **emoji_particle** (main.lua:684–748): emoji sprite; scale normalized so scale=1 → **14 px wide** regardless of source PNG; velocity default random(75,150), duration random(0.4,0.6); rotation_speed random(−4π, 4π) unless angle_mode ('forward'/'backward'/fixed number); tween velocity+scale→0 linear; flash_on_spawn can be a **fraction of duration** (e.g. 0.3 = flash for first 30%); spawn flash also pops spring (0.3, 3, 0.7).
- **damage_number** (main.lua:761–820): per-digit keycap sprites (0..9.png + plus.png), digits ~12 px (scale 12/512); rises at vy = −80; duration_multiplier 0.5 — holds full scale 25% then shrinks to 0 over 75% cubic_in_out; per-digit wobble: rotation random(−π/16, π/16) + angular_speed random(−π/4, π/4), bob `offset_y = 2·sin(time + i·0.3)`; spawn spring pull (0.5, 3, 0.7); rendered to digit_layer and **recolored per rarity_color bucket via recolor.frag** (draw pass 5586–5610). Tier ladder SCORE_TIERS (1909–1916): 1-10 gray, 11-25 green, 26-50 blue, 51-100 purple, 101-200 orange, 201-500 red (in practice all hit popups pass `{color = blue}`).
- **miss_x** (main.lua:2765–2799): gray X sprite recolored **red** via the damage-number pipeline, 20 px, rotation random(±π/8), spring pop (0.5, 4, 0.5); solid 0.15 s, then blink via `timer_during_step(0.22, 0.08, 0.03)` (accelerating flicker), then die.
- **stuck_arrow** (main.lua:1029–1065): visual arrow lodged in wall/floor; holds random(0.9,1.0) s, then flickers every 0.1 s ×6 toggles, dies at +0.65 s; drawn behind_walls so wall fill covers embedded part; embed offset = random(0,10)·|cos(angle)| (walls) or ·|sin| (floor) so tip stays plausibly embedded at grazing angles (908–1003).

**Burst recipes (counts / velocities / durations):**

| Event | Recipe | Cite |
|---|---|---|
| Normal hit | hit_effect s1 + 2 yellow hit_particles (vel 120–200, dur 0.25–0.6, gravity 256, flash) + 1 star emoji (vel 80–150, dur 0.3–0.8, scale 1, gravity 256, flash 0.25) | 2199–2219 |
| Dagger kill | hit_effect s1.5 + 6–9 **red** hit_particles (vel 140–320, dur 0.3–0.7, gravity 256–512, w 8–14, h 4–8, flash) | 2184–2196 |
| Target death | 2–4 yellow capsules (vel 100–350, dur 0.4–0.8, gravity 228, w14 h8, flash) + 2 stars (vel 120–240, dur 0.6–1.2, scale 0.8–1.2, spin ±4π, gravity 256, flash 0.3) | 2311–2334 |
| Target spawn-land | 3 direct_hit emojis (vel 140–200, dur 0.3–0.5, scale 1.0–1.2, gravity 0, flash 0.3) | 2072–2081 |
| Chili chain hit | 1 chili emoji (vel 60–120, dur 0.4–0.6, **scale 2.0**, gravity 0, flash 0.3) | 2257–2264 |
| Bone hit | 3–5 bone emojis (vel 80–180, dur 0.4–0.7, scale 0.8–1.2, gravity 250, flash 0.3) | 2277–2286 |
| Arrow hit | 2–3 arrow emojis (vel 80–160, dur 0.3–0.6, scale 0.8–1.2, gravity 200, flash 0.3) | 2295–2304 |
| Gun muzzle boom | 3–5 yellow particles (vel 80–180, dir ±π/6 cone, dur 0.15–0.3, no gravity, flash) at tip offset ~33 px | 1646–1655 |
| Resource collect | 3–5 copies of the resource emoji (vel 80–180, dur 0.3–0.6, scale 1.0, **gravity 0** — radial drift) + white ring + "+value" number | 2908–2924 |
| Shop buy (cursor) | yellow ring + 4–5 coin emojis, dir upper hemisphere (−π..0), dur 0.5–0.8, scale 1.0, gravity 250, flash 0.3, on shop_particle_layer | 4657–4671 |
| Shop buy (slot) | 4–5 bought-item emojis (vel 40–100, dur 0.35–0.6, **scale 1.3**, gravity 0, flash 0.3) | 4679–4689 |
| Level-up (dup buy) | 8 blue hit_particles at badge pos (vel 40–100, dur 0.3–0.5) | 4595–4604 |

**Projectiles:** bone_strike (speed 150, spin 3π rad/s, 16 px, spawns at y=−30 falling in, chases nearest-alive with hit_set; 839–895); arrow_strike (speed 600, gravity 400, scale 26/512, image angle offset **3π/4**, pierces, ricochets via 8-ball charges; 908–1021); bullet (15×8 yellow rounded rect, speed 340, base 2 bounces; 1072–1152); boomerang (speed 220, spin 12π, turn rate 3.5 rad/s outbound flips to homing 6 rad/s after t ≥ π/turn_rate, catch radius 15 min-time 0.5 s, sprite offset −π/2+π/4+π/16; 1160–1249).

**Transitions:** yellow circle wipe from cursor (SNKRX TransitionEffect pattern) — in 0.6 s **linear** to radius 1.2·gw, hold 0.3 s (state swap at mid), out 0.4 s cubic_out; recenters on current cursor pos for the out phase; circle drawn on outlined transition_layer so the wipe itself has a black border (main.lua:152–155, 4898–4941, 5558–5561). Payout variant holds at 'mid' indefinitely until click.

**Environmental dressing:** vertical sky gradient sky_top(135,206,235) → sky_bottom(231,232,233), drawn **camera-attached and inflated 32 px** on all sides so punch-zoom/handcam never expose corners (5375–5378); cream side walls (fg color) 105 px wide each with WALL_BLEED 10 px overflow (169–175, 5395–5400); no clouds/plants/wind in this one. Shadow pass: whole game+effects layers re-drawn through shadow.frag at offset **(4, 4)** (5659).

---

## 5. UI

**Layer/outline architecture** (main.lua:202–283, 5573–5680): 13 content layers each with a derived `_outline` sibling produced by outline.frag every frame (`layer_draw_from(outline, layer, outline_shader)`); composite bottom→top: bg → shadow(+4,+4) → game_outline/game → effects_outline/effects → ui_panel → ui_content → ui_top_panel → ui_top_content → overlay → shop_particle → cursor → transition → payout. Panel vs content split so text/icons get their own halo; ui_top pair exists **specifically so tooltips overlapping tiles get separate outlines instead of merging silhouettes** (222–230). UI layers are camera-attached in-round (chips wobble with the handcam) but NOT in shop (5419–5426); cursor/overlay/transition always screen-space.

**Fonts** (360–363): 'main' LanaPixel 11 (body), 'big' FatPixelFont 8 (chunky headers), 'mid' Awesome 9 @ 16 (score/headlines), 'debug' LanaPixel 11. Recurring vertical-centering recipe: `floor(y + h/2 − 11/2 + 1)` (+1 more in banners) because "LanaPixel sits high in its 11-px box" (3135–3137). Text x always `math.floor`-snapped — explicitly noted as fixing glyph-spacing breakage (3942–3947).

**In-round HUD:**

- Left wall stack (top inset 8, chip gap 6; 5440–5472): timer chip (hourglass icon, `%02d:%02d`, fixed width via min_text_w of '88:88' so digits don't twitch), gold chip (coin icon, min width '9999', gap 6), then 3-col owned-items grid.
- **HUD chip recipe** (3108–3142): cream (fg) rounded rect r=2, pad_x 3, pad_y 5, icon 14 px, gap 4 (6 for tight-bbox icons), text white on ui_content (outline pass makes it read).
- **Score panel** (3154–3177): blue 64×34 r=3 pinned to right wall column top (y 8), big score (Awesome 16) over "/ target" (LanaPixel) — Balatro-style; y offset by cash-register kick.
- Multiplier panel (3183–3200): blue 32×20 r=3, "x2" etc., hidden without Bacon, own kick.
- Buff stack (3206–3257): shield panel 32×20 fg, icon 12 (dimmed fg_dark at 0 charges), "X/Y" text, 2-px blue recharge progress bar at bottom (only while below max).
- **HUD inventory** (3269–3355): 3 cols × 28 px slots, gap 6, icon 16, at x centered in 105-px wall, y 68; hover = white frame + spring pop + wobble + tooltip (name + desc, **no price** — "items only have a price in the shop context", 4063–4066); count badge = blue-recolored keycap digits 10 px at slot top-left riding the slot transform (4221–4242).
- Cash Out / New Run buttons: 96×22 at bottom-right (120–123); primary green, hover white, springy panel + static text.
- Won/Lost overlay (5517–5539): title Awesome centered (gh/2−16), lost adds death_reason + "SCORED X / Y" lines (gh/2+6, +20).

**Shop screen (subtle points beyond the already-skinned kit):**

- Tile 48×48 r=6; banner band h=14 drawn as rounded rect + **two corner-notch-fill rects** so its top edge is flat — this notch trick recurs in tooltip header (4053–4056) and tier-strip segment highlights (4131–4150).
- State logic: banner yellow=affordable / gray=not / red=error; frame white=hover / fg_dark=unaffordable / red=error; unaffordable emoji routed through **grayscale_layer → grayscale.frag** so the outline derivation sees a true-grayscale silhouette (3906–3940, 5612–5620); error suppresses grayscale and tints emoji+label red so the whole tile reads as one red shape.
- SHOP_KIT_WOBBLE_MODE = 'card' — a deliberate toggle ('emoji' variant kept for comparison, 3565–3567).
- Sold tile renders **nothing** — "the tile is gone", not an empty box (3849–3851).
- Tooltip: pad 6, line_h 12, header_h 16, min_w 130, r 6, coin 9 px, desc wrap 130; greedy word-wrap (3976–3996); header color tracks affordability; positioning: right of element gap 4, flip left on overflow, clamp 4 px to all edges (4095–4106).
- Grid 5×4 from x 96 y 34 gap 8; owned column 2×6 of 28 px at x 393 y 34 gap 6, icon 16; tier strip 4×68×18 at (96, 8) — active fill green, hover white, locked segments show 12-px padlock emoji, dividers skipped adjacent to active (4160–4206); left column: SHOP frame 70×34 at y 8, gold chip below at y 50, NEXT ROUND 70×18 at y 244.
- Locked-section overlay: rgba(48,49,50,200) band + 24 px padlock (4307–4314).
- Tooltips are **count-aware**: description text is generated from the player's current stack (`desc_at(count)`), unowned previews show count=1 (3823–3835, 4806–4814).

**Payout screen** (3378–3553): three-column (label/amount/detail) left-aligned lines; per-line animation = 6-px drop settling over 0.2 s + strictly sequential L→R typewriter at 50 chars/s (label→amount→detail); line stagger 0.4 s; separator 1-px white with 6-px overshoot; TOTAL after +10 gap; hint 'CLICK TO CONTINUE' types after 0.15 s pause then blinks 0.5 s on / 0.4 s off; click-to-skip fast-forwards elapsed to computed `PAYOUT_FULL_TYPE_T` (≈2.29 s, derived from constants so tuning stays in sync, 3393–3407); second click advances.

**Number formatting:** `format_with_commas` for gold/score (4392–4396). Displayed values always lag real values via cubic_out scrub-tweens so numbers visibly count.

---

## 6. SOUND

**None.** The game is fully silent: no audio assets in `assets/` (verified listing), no sound module in `anchor/`, zero sound/music/audio/play/volume references in main.lua (grep-verified — see above). For the template generalization: this game contributes nothing to the sound catalog; pitch/volume conventions must come from the sibling games (EBB / super-emoji-pop / emoji-ball-bounce).

---

## 7. STYLE CONSTANTS

- **Palette** (main.lua:27–57): white(255,255,255), black(0,0,0), gray(128,128,128), bg_color(48,49,50), fg(231,232,233) [cream — walls/panels], fg_dark(201,202,203) [disabled], yellow(253,205,86), orange(244,146,0), red(223,37,64), blue(83,175,239), green(122,179,87), purple(172,144,216), brown(193,105,79), pink(244,154,194) [new in this game, "blossom pink from UI kit"], bowstring(217,158,130). Medal colors sampled from Twemoji 1f947/48/49: bronze(248,136,56), silver(200,208,216), gold(248,168,48) — note the **medal_gold alias** because the `gold` global gets reassigned to the currency integer (46–54, a real footgun the dev documented). Sky: top(135,206,235), bottom(231,232,233). Colors are **callable** tables — `white()` returns packed rgba int (anchor/color.lua:78+).
- **Outline** (`assets/outline.frag`): 24-sample 5×5 neighborhood alpha sum, clamped, output pure black at that alpha — a ~2-px chunky black silhouette; `u_pixel_size = (1/480, 1/270)` (main.lua:292).
- **Shadow** (`assets/shadow.frag`): `vec4(0.5, 0.5, 0.5, a·0.5)` — 50%-gray half-alpha silhouette, composited at offset (+4, +4) (main.lua:5659).
- **Recolor** (`assets/recolor.frag`): keycap gray (120/255 ≈ 0.471) → u_target_color, white stays white via `t = (gray−0.471)/(1−0.471)` mix. Used for damage-number rarity tinting and blue level badges (u_target_color 83/175/239, main.lua:5627–5628).
- **Grayscale** (`assets/grayscale.frag`): Rec.601 luminance (0.299/0.587/0.114), alpha preserved.
- **Emoji sizes:** targets 24 px (2×radius), cursor 22, shop tile icon 22, HUD icon 16/14, tooltip coin 9, digits 12, resources 13/13/16 (coin/gem/crown), particles 14×scale, bone 16, arrow 26/512, boomerang 22/512, weapons 26/18/28/22 (bow/gun/sword/boomerang).
- **Cursor:** hidden OS cursor (`mouse_set_visible(false)`, 5098); 👆 backhand emoji at inner offset (+7, +9) with base rotation −π/8 "calibrated in super-emoji-pop so the fingertip lands at self.x/y" (2624–2631); contextual sprite swap: skull (offset 0) &gt; dagger (offset 5π/8) &gt; backhand (2544–2557).
- **Fonts:** LanaPixel 11 / FatPixelFont 8 / Awesome 9 @ 16 (matches the MEMORY.md warning that FatPixel renders huge — registered at only 8 here).

## 8. DISTINCTIVE (mechanics-agnostic tricks worth generalizing)

1. **Cursor-as-character** (2432–2637): the mouse pointer is a fully juiced entity — momentum sway (10-frame delta history, fires on *stop* after fast motion), velocity-proportional squash, click press/release squash-and-rotate, item-state sprite swaps, a stab lunge, an error persona (red X, deliberately *stripped* of all spring/rotation so it reads as a stamp), and sympathetic 0.05 pulses acknowledging every UI hover. The cursor lives on its own outlined layer, exempt from handcam so the fingertip stays pixel-true.
2. **Combo escalation ladder** (1945–1964, 2649–2755): 10 flat bands of 10; color heat ramp white→blue→green→yellow→orange→red→purple then **bronze→silver→gold medals** as tiers 70/80/90 — prestige encoded purely in color; per-tier jitter amp (0→4 px) AND duration (0→0.45 s) both scale so a fresh gold hit reads much bigger than a fresh yellow; shake params are *captured at trigger time* so a tier-up shakes for the full new-tier window (2655–2661); combo display follows the cursor (+16, −18) with a tilted Awesome number, tier-colored, coin icon appears only when the tier actually drops coins, and a 16×2 yellow drain bar shows the decay window.
3. **Punch-zoom solved around the hit point** (2175–2183): camera position computed so the world hit point stays at the same screen pixel under 1.5× zoom — "the punch reads as a zoom, not a translation." Paired with rotation-only trauma (amplitude {0,0,0.18,0}) and 0.33× slow-mo for the instakill sandwich.
4. **Layered outline discipline**: separate outline pass per UI tier (panel/content/top/cursor/transition/payout) exists to prevent silhouette merging — overlapping outlined elements each keep a crisp border. Even the screen-wipe circle and the payout text get their own outline layers (269–281).
5. **Cash-register kick pattern** (repeated 4×: score chip, gold chip, mult panel, payout lines): value scrubs via cubic_out lagging display + panel body snaps down 3–4 px and *linearly* rises back — snap-down/ease-number is the house style for "money moved."
6. **Deterministic named-tween replacement** as a global convention (see §3) — every re-triggerable juice tween is named so spam replaces rather than stacks.
7. **Vacuum-then-transition round end** (2881–2951, 5249–5251): on cash-out, all field resources ignore range and race to the cursor; the wipe only starts when `any_live_resource()` is false — reward collection is forced into a physical, watchable beat.
8. **Resource physicality** (74–115, 2814–2864): per-kind Box2D shapes (circle coin rolls, 5-vertex diamond gem tumbles, box crown rocks), restitution 0.7, upper-hemisphere pop 160–280 px/s, angular velocity ±3π, 0.6 s arm delay so "the player sees the burst before it gets vacuumed", magnet pull with t^0.3 activation snap and doubled upward force.
9. **Payout typewriter ledger** (3378–3553): drop-in + strictly sequential per-segment typing + skip-on-first-click computed from the same constants — a self-consistent reveal system.
10. **Recolor-pipeline text**: numbers are emoji keycap sprites bucketed by color and shader-recolored per bucket — one gray asset set serves every tier color, including the red miss X (which needed its own flat-gray source asset, x_mark_gray, to round-trip the shader — 303–309).
11. **Per-tile handcam with randomized phase** (4401–4408): each shop tile carries its own miniature handcam shake (started at random time 0–100) faded by hover_amount — hovering literally "picks up" the card.
12. **Camera-attached background inflation** (5371–5378): the sky gradient rides the camera and is drawn 32 px oversized precisely so punch-zoom/handcam can never expose void — the fix that makes the punch feel like the *world* scaling.</result>

The emoji-aimer catalog came back with excellent detail, so I need to preserve it before context gets summarized. I'm saving each agent's results to a scratchpad file as they arrive, starting with writing the full catalog verbatim to scratchpad/catalog_emoji_aimer.md since having the exact text in context makes that the safest approach.

File created successfully at: C:\Users\adn\AppData\Local\Temp\claude\E--a327ex\a348cf7a-e979-478b-a7c8-af2429a3d98f\scratchpad\catalog_emoji_aimer.md (file state is current in your context — no need to Read it back)

Five catalogs are already in place—aimer, invaders, merge, emojunky, and small-prototypes—but I still need to handle the remaining four: EBB, box duo, pop duo + pairs, and connect+guncraft+emojian. Since these are quite large, I'm going to save them to scratchpad files rather than trying to write them all at once, which would mean a lot of individual write calls with massive content blocks.

Four more catalogs arrived and I've confirmed that invaders is the feel-richest single game. I'm banking each one verbatim before the remaining four agents land.

I've got two more catalogs loaded in, with a couple still pending. Now I need to write out the merge, emojunky, small-prototypes, EBB, and box catalogs to scratchpad files—that's five more write operations with substantial content. I'm going to batch these together and execute them now.

I've processed two more catalogs—emoji-ball-battles with its advanced systems and both box versions, which uncovered some latent bugs to avoid copying. Now I'm banking the remaining catalogs.

queue check

Eight of the nine agents are complete, with just the pop duo and pairs agent left to finish. I need to save five pending catalogs to scratchpad—merge, emojunky, small-protos, EBB, and box—though actually that's six items including connect-trio. Rather than re-emit all the catalogs verbatim, which would consume a lot of tokens, I'm reconsidering the approach around notifications.

The full text is already in the conversation, so the main risk is context summarization. The synthesis step is the priority once the last agent finishes, and doing it promptly means I can cite directly from context. The deliverables will be a reference doc in emoji-template/reference/ and the full chat, both as distillations rather than full reproductions. Since the user wants the research preserved for future instances, I should save the verbatim catalogs as per-game files in emoji-template/reference/ rather than scratchpad—they're research artifacts that belong in the repo, not in a session-bound location. The per-game catalogs plus a synthesis doc is the right structure.

Writing to emoji-template/ counts as a project change, but reference docs are exempt under the design-brief rule, especially since the user explicitly asked for a thorough pass compiled. I'll write the per-game catalogs to emoji-template/reference/emoji-style-research/ as I bank them, which serves both as banking and final artifact location. The cost is re-emitting roughly 30-35k tokens of content, which is substantial but that's the actual deliverable the user requested—they want this research to inform the generalizable build going forward.

I'll balance this by banking the raw catalogs to reference files while delivering the synthesis in chat: a cross-game matrix, verdicts, gap analysis, and recommendations rather than verbatim repetition of all nine catalogs. Now I'm writing the six pending catalogs to files, one per call to manage output size. Each catalog runs 3-6k tokens, so roughly 25-30k total for all six writes. I'll place them in emoji-template/reference/research/catalog-<game>.md and let the Write tool create parent directories as needed.

My approach: use PowerShell to create the directory and copy the three existing scratchpad files (aimer, invaders, sound_findings) into that folder, then write the six remaining catalogs directly there, bank the pop/pairs catalog when it arrives, and finally deliver the synthesis.

Eight of nine agent catalogs are complete, with the connect/guncraft/emojian catalog revealing that emojian shipped the family's only active distance-attenuation sound system and that engine semantics are byte-consistent across generations. I'm archiving these research catalogs to `emoji-template/reference/research/` for future reference.

All nine agents have completed their work. The pop/pairs catalog revealed something important: the 2024 "super emoji pop" is actually called 'super emoji clicker' internally and represents a post-mortem redesign, which ties into the design principle about stateless enemies that's relevant for the showcase. Now I need to archive the remaining six catalogs—emojunky, small-prototypes, EBB, box-duo, connect-trio, and pop-pairs—into the emoji-template reference directory.

I'm deciding whether to write out the full verbatim catalogs or compress them. The synthesis document will contain the critical values, but the per-game tables in each catalog are genuinely useful for the build, especially for EBB's mechanics, box's movement and plants, pop/pairs' cursor and UI details, and emojunky's movement origins. I'll bank all six in full since they're the archival record the research depends on.

I'll write them in pairs per response to stay within output limits—starting with emojunky and small-prototypes, then moving through EBB, box-duo, connect-trio, and pop-pairs before synthesizing everything together.

All nine catalogs are in, and the final one reveals a key design principle from the 2024 pop reboot's post-mortem that's directly relevant to the showcase. I'll now bank the remaining six catalogs.

Now I'm organizing the synthesis into key sections: establishing what the family invariants actually are across all the games, mapping out which elements appear in which titles, comparing that against the current template to see what's confirmed, contradicted, or missing, and then drawing conclusions about both the core mechanics and the showcase coverage.

Let me work through the gap analysis systematically by checking the template files against what I found in the catalogs. Starting with the juice system: the template's hitfx defaults use specific spring parameters (force, frequency, bounce), and I'm cross-referencing those against what EBB and Aimer actually implement. EBB's damage response matches the template's hit pull signature pretty closely, though there's a minor discrepancy in the bounce values between the initial setup and the re-pull that's worth flagging. Aimer's target hit behavior aligns exactly with the template's hitfx_hit defaults, so that's confirmed.

Now checking the squash formula—the template uses the same amount/−amount*0.5 pattern as EBB, which is confirmed, but EBB applies a 0.75 intensity multiplier while the template borrowed ball-bounce's gentler 0.4 factor instead. The wall_hit_intensity easing (cubic_in_out below half, circ_in above) matches both EBB and ball-bounce. For slow_time, the template uses an instant dip with cubic_out restore, which aligns with what Aimer does engine-wide, and the specific values from the dagger kill slow_time are starting to come into focus.

Two canonical slow-motion recipes are emerging: the reward-slam uses 0.33/0.5, while the hurt-slam uses 0.5/1.0. Camera punch is confirmed at 0.03 cubic_in in and 0.5 cubic_out out with a 1.5 zoom, matching Aimer exactly. The handcam offset and rotation trauma values are also confirmed across multiple sources.

I'm noticing some critical gaps in the template juice that need addressing: hitstop mechanics with frequency-aware probability gating, directional spring-shake for landings using the spring-push channel convention, and landing squash grammar with specific velocity remapping and spring constants. The camera behavior is cut off but seems to be part of this missing piece. Idle wobble pulses trigger randomly every 0.4–0.6 seconds, and there's a hit-face swap idiom where the emoji face changes to dizzy for 0.2–0.35 seconds — that's consistent across the 2022 games and other titles. For the hit_circle effect, the template uses a default yellow with cubic_in_out easing over 0.2 seconds, but I'm noticing the research shows a two-tone color swap at half-life (color_1 → color_2) that appears in invaders, EBB, pop, connect, and box — the template has flash_on_spawn but not that mid-life color transition yet.

Looking at the hit_effect timing, the template's 0.03s per frame with 1.35 scale matches Aimer's approach, though other games vary between 0.02–0.05s. The hit_particle dimensions (width remapped to 4–12, height to 2–6) align exactly with EBB and Aimer, while the 2022 games use a wider range. This confirms the template's Aimer lineage. Now examining emoji_particle behavior...

For damage_number, the keycap digits at 12px with vertical velocity of −80 matches Aimer's implementation, which is newer than the −24 velocity used in EBB and other games. The 25% shrink and 75% hold timing are confirmed across versions. The per-digit wobble applies rotation and angular velocity with halved amplitude as noted in the template.

The bob animation uses a sine wave with a phase step of 0.3 per digit, which matches Aimer's catalog exactly — the template didn't halve this after all, just adjusted the phase progression. For the missing FX classes, emoji_particle already generalizes star_particle functionality, so that's covered. Still examining boom_particle... The despawn effects include a universal blink-out helper, afterimage ghosts, and an explosion effect that transitions from white to black. There's also stuck projectile debris and enemy corpse physics with bisection. For the miss marker, the template uses a simple zero-velocity emoji particle, but the real implementation needs a red-recolored X that springs in, holds solid briefly, then accelerates into a blink-out — I need to replace the placeholder. Now looking at the pipeline configuration with outline and shadow settings. I notice the outline_only fragment shader is missing from the template even though EBB used it for the HP heart display. Looking at cursor.lua, the values match exactly across Aimer and POP24 catalogs, but there are some contextual features not yet implemented—sprite swapping for different cursor states and an error persona with a red X mark that deliberately avoids spring animation.

For sounds.lua, the pitch variation of 0.95–1.05 is confirmed as standard practice. Volume levels follow a clear hierarchy from quiet movement sounds around 0.05–0.15 up to major events at 0.7 and above, with frequent events like player hits and landings sitting around 0.35. The convention is to create 2-3 variations per common sound event and layer pairs for UI interactions.

For pitch manipulation, lighter shots get pitched up to 1.2–1.5 while heavier impacts drop to 0.5–0.7, and combo repeats escalate pitch incrementally. Sound gating prevents fatigue, and distance attenuation applies in certain contexts. Music is minimal across the shipped games, though there's some debug music and a Recettear track at reduced volume. The template's runtime bitcrush effect is a new engine capability worth noting.

For UI, I've already identified the aimer skin, and now I'm seeing there's a payout typewriter LED element to incorporate.

The text tag system from the 2022 engines—wavy, color, typewriter, and flash effects—isn't in the template yet, but the item-choice screens use wavy titles. Those screens have a distinctive look with stacked boxes, hover effects, parallelogram sheens, mirrored bobbing emojis, and layered audio that's worth preserving. The HUD digits also have a bouncy drop animation with staggered spring timing that gives it a cash-register feel.

The template has the UI bar feed and HUD chips, and there's a mention of the two-bar HP tween plus the cash-register kick effect, though it's only partially implemented. For the remaining movement juice, I'm looking at the full canonical set from research—hop movement, jump arcs with specific gravity values, landing squash remaps, camera kicks, dust particles, layered land sounds, air spin and snap, plus face swaps. There's also the plant and wind system with exact constants and some phase timing considerations to watch for, along with cloud generation using Poisson disk sampling.

On the sound side, the verdict is that the commonality is real—there's a curated bank with universal conventions around pitch jitter, volume variations, and layering. The recommendation is to ship the sound bank in the template itself since the showcase needs sounds anyway; the template assets become the demo set while the emoji/sounds wrapper maintains the nil-safe conventions. Since the showcase lives in the template's main.lua, the assets will be there regardless, and we can codify the conventions as data or documentation for forks to reference later.

Super Emoji Invaders emerges as the richest single game to showcase—it demonstrates the full movement vocabulary through hop-platformer mechanics with jump, land, squash, and dust effects, three distinct weapons with projectile variety and recoil, three enemy types with telegraphs and spawn/death effects, waves with an item-choice screen, environmental elements like plants and wind, and a complete HUD with damage numbers and tooltips. It uses over 30 sound triggers from the bank. The gap to fill is pulling in features the template has elsewhere—like the shop and card UI from Aimer—to round out what Invaders doesn't yet demonstrate.

I'm thinking through what to graft in: an economy system with gold drops and coin vacuum mechanics to test the cash-register sounds, the cursor showcase (Invaders has a pop effect but Aimer's template cursor is more complete), screen effects like slow-mo and punch-zoom tied to critical hits or last-kill moments, hitstop on melee impacts or as a telegraph spike, and optionally a score or combo ladder. The slice needs to sit between waves as a shop phase that leverages the existing card and tab UI.

For the actual deliverable, I'm planning to structure this as a thorough but readable chat response: start with a research headline, lay out the confirmed family invariants, call out what each game contributed, analyze what's confirmed versus missing against the template, then give a sound verdict with a concrete recommendation for the showcase slice scope.

I'll also write a synthesis document that captures the matrix and verdicts in condensed form, with the chat message serving as the primary delivery and the doc as a reference mirror. Since this will be lengthy, I'll end by batching the key decisions—the shipping choice and slice scope options—without jumping into implementation yet.

All nine catalogs are now stored in the research folder. I'll cross-check them against each other and the template's current implementations to write the master synthesis document.

I need to pull together the full analysis for the chat message, covering what was researched, the canonical family rules, the major systems and their values, where the data confirms or contradicts expectations, and what's still missing—then wrap up with the key shipping decisions around sound and scope.

The user wants me to skip the design brief and build a complete, playable game example first, then extract reusable patterns into a template afterward. For the scope, they've chosen the invaders-faithful approach with the shop graft. On sounds, they're deferring the final decision but want the game itself built with audio included.

Now I'm mapping out the full showcase game: a space invaders-style platformer with hop movement, multiple weapons and enemy types, wave progression, an item-choice screen with procs, plus an Aimer-inspired shop between waves with coin drops and card affordances. I'm also adding a reward-slam event with slow-motion and impact effects, environmental elements like plants and wind, and a complete HUD showing health and gold.

The new systems I need to build—hitstop, landing mechanics, spawn effects, telegraphs, particle effects, sound layering, face swaps, camera work—all go into main.lua first, then get extracted into the template later. I'm using the existing emoji toolkit as-is and deferring fixes to contradicted items like transition origin until the extraction pass.

For the transition wipe that needs to originate from the player instead of center, I could either extend the toolkit with optional x/y parameters or write a game-local wipe. I'm leaning toward keeping all new code in main.lua and writing the wipe there using a transition-like pattern, passing options through the existing transition layer without modifying the toolkit unless absolutely necessary.

Now I'm settling the core game structure: I'll use 480×270 scale (matching the template standard rather than invaders' 640×360) with a hand-authored platformer arena using solid rectangles for the floor, platforms, and walls. The player will use hop-based movement with Box2D physics from the template's collider system.

For weapons, I'm starting with a gun that has recoil and muzzle effects, then adding a dagger as a thrown projectile that can stick as debris. The player begins with the gun and can unlock the dagger through shop purchases, giving me coverage across ranged and melee options without overcomplicating the initial loadout.

For enemies, I'm planning an alien that charges and shoots telegraphed bullets, a cloud that flies and strikes with lightning while splitting into smaller versions, and a clown that teleports when hit with escalating pitch sounds. The alien and cloud give me multiple attack patterns and visual variety, while the clown adds a distinctive cheap mechanic—three enemies total to match the scope of the original game.

For progression, I'm structuring it as: clear a wave, then show an item choice screen with three boxes in an invaders-style UI, followed by a shop screen with card-based widgets before the next wave starts. This way both UI styles get showcased each round, and coin drops from enemies fund the shop purchases. Coins get collected on player touch with sound feedback and a counter update. The shop displays purchasable items as cards with tooltips and pricing, plus maybe a dagger weapon. For the reward moment, I'm thinking the last enemy of each wave triggers a big slam effect—slow motion, screen rotation trauma, and a punch-zoom at the kill point—which gives that satisfying wave-clear beat. Regular kills also get hitstop with a recency gate to avoid spam.

Game over happens when the player dies, then shows a loss screen with a wipe transition and retry option. Winning after wave 5 brings up the win screen. The HUD displays health with a count-up/down animation, a gold counter that kicks on pickup, the current wave number, and an inventory tray showing owned items with tooltips. Damage numbers pop up on enemy hits, and gold pickups show a "+1" style text effect. For atmosphere, I'm layering a sky gradient with drifting clouds, plants on the floor and platforms with wind animation, and possibly a subtle screentone effect in the background.

I'm using the template cursor (finger pointer like in Invaders), adding wavy text animation to item names on the choice screen by drawing each character with sine-wave offsets, and implementing circle wipe transitions between screens. For audio, I'm pulling a subset of sounds from the existing emoji-template library and mapping them to invaders/Aimer conventions—layered pairs, escalating teleport pitches, pitch-up effects for candles, and distinct sounds for the gun and dagger weapons.

Now I need to grab the Anchor 2 API documentation to understand the physics collider system, input handling, timers, springs, layer management, and sound playback before I can implement these mechanics properly. The user wants the full game built in one go since they explicitly asked for it, so I'm committing to writing the complete main.lua file (~2500+ lines). I need to read the current emoji-template/main.lua, FRAMEWORK_API_QUICK.md, and the emoji module files to understand the palette names and UI widget structure before I start building.

Now I'm checking what emoji assets I need for the game—player faces, enemies like aliens and clouds, weapons, food items, plants, and various effect sprites—and figuring out which ones I already have in the template versus which ones I need to download from the emoji CDN or pull from existing game assets. I'm debating whether to set up formal task tracking for this multi-step build, but I'll just proceed carefully without it. First I need to read through the template's main.lua file and the framework API documentation to understand the available functions for physics, input, timers, sound, camera, collision events, and image loading, then check what's preloaded in the emoji module and review the UI widget signatures.

I've identified the widget components I need for the shop and HUD interface. Now I'm moving on to gathering the asset requirements, starting with the Twemoji PNGs for the player character and other game elements.

For the player, I need the smile face (already have it) and a dizzy face for the hit state instead of the original no_mouth variant. For weapons, I'm using pistol and dagger emojis, with the gun firing a simple yellow rounded rectangle and the dagger using its own image. The enemies are the alien emoji (👽) and a cloud that can reuse the existing cloud image but with a darker tint to distinguish it from the background dressing. I'm also gathering item assets including fire and hot pepper emojis. I'm planning to download about twenty emoji assets through the skill endpoint, including the water pistol (which Twemoji updated to a squirt gun), dagger, alien, clown face, fire, and hot pepper along with the ones I already listed. I could also pull these from existing project assets instead if that's faster.

Looking at what's available in the emoji-ball-battles and emoji-aimer projects, both have 512×512 PNG assets that cover most of what I need — the EBB assets include plants, weapons, and hearts, while the aimer assets have a broader set with fire, coin, coffee, and other items. Copying from these existing sources would be more efficient than downloading, so I'm going to inventory what both projects have and grab what overlaps with my needs. For anything missing from those asset lists, I'll check the EBB folder first since it has plants and other elements, then use the download skill for the rest. On the sounds side, I'm copying the needed audio files from the bank — hop, various grass and impact sounds, player and enemy audio, and the weapon shots — making sure to grab the right variants like enemy_die instead of enemy_death where the bank has both. ocked_hover, ui_click_neutral, ui_click_tab, ui_click4, ui_click5, ui_error, ui_success, ui_hit, player_hit1/2 — the bank has all 57 of these files. I'm cross-referencing with invaders' sound assets, which also includes melon, revive, spawn, and pop. Looking through the bank's complete listing to verify what's already there versus what needs to be copied over from invaders. I'll copy the entire sound bank into assets/sounds and add the missing files from invaders. For the game design, I'm keeping the demo as "SUPER EMOJI INVADERS" slice with the scene named accordingly, maintaining the 480×270 resolution at 3x scale like the template standard, matching invaders' setup.

For sizing, I'm scaling down the invaders emoji proportions — player at 18px and enemies at 18-20px to fit the smaller resolution, similar to what the older 480×270 games used. The arena will be a single-screen platformer layout with a ground floor, 2-3 floating platforms, and side walls, using a sky gradient background with a cream-colored play area backdrop like invaders' light floor rectangle.

Now I'm mapping out the game flow: arena for active play, item_choice as an overlay when a wave clears, shop as its own screen, plus won and lost states. The progression goes wave cleared → reward animation on the final kill → item_choice overlay (pausing spawns while the player picks) → shop screen (transitioned with a wipe) → next wave button → back to arena with fresh spawns.

I'm reconsidering whether two interstitials per wave will feel slow, but since this is a showcase, having both the item choice and shop each time is fine. For the five waves, I'm planning escalating difficulty: wave one starts with just aliens, wave two adds more aliens, wave three introduces clowns, wave four brings in clouds, and wave five mixes all three enemy types with higher counts. Rather than spawning in organized groups, I'll simplify to spawning one enemy every half second at random positions near the top using a spawn effect, which keeps the pacing consistent.

For enemy behaviors: aliens will be grounded hoppers that move toward the player and deal contact damage, plus they'll telegraph and fire trailed bullets. Clouds float without gravity, drift horizontally above, telegraph for a brief moment, then strike with a lightning bolt column below that has visual effects and sound. When clouds die, they split into two smaller clouds. Clowns hop around randomly on the ground, and whenever they take a hit they teleport away to dodge.

For the player: 5 HP displayed with a heart icon in the HUD bar. Movement uses the same platformer physics as the invaders game—specific velocity caps, hop and jump values, and air control with landing feedback. Getting hit triggers 2-second i-frames with a blinking effect plus a hurt animation with slowdown and screen shake. The weapon orbits 32 pixels toward the mouse and auto-fires while the mouse button is held, with a cooldown between shots.

The gun fires straight yellow bullets that bounce twice before disappearing, with muzzle effects and recoil feedback. The dagger is a thrown spinning projectile that bounces off walls with physics-based restitution, damages enemies on contact, and embeds into walls after a certain number of bounces before fading out. Each weapon has its own sound effects and firing rate—gun at 0.5 seconds, dagger at 0.8 seconds. Players start with the gun and can purchase the dagger from the shop, then switch between them.

For the wave-clear moment, I'm triggering a reward-slam effect on the final kill of each wave: slow motion, screen rotation trauma, a punch-zoom at the kill point, and layered critical hit sounds for that satisfying stinger. For hitstop feedback on kills, I'm implementing a time-scale freeze that's gated by how recently the last kill happened, creating a brief pause that feels responsive without being overwhelming.

The tricky part is handling the hitstop correctly—I need it to freeze time completely (scale to 0) for a short duration, but the juice system's recovery tween runs on scaled time, so it would never recover from a 0 scale. The solution is to track hitstop separately using unscaled delta time in the update loop, so the freeze duration counts down independently of the game's time scale.

For the item system after each wave, I'm picking 3 random items from a pool of 6: fire adds a burn effect with damage over time, chili chains hits to nearby enemies, melon blocks one hit per wave, mushroom revives the player once, and coffee boosts attack speed.

I'm also adding hotdog which increases max HP and heals, with stacking allowed. The item tray displays in the bottom-left corner with 22px emoji icons and tooltips on hover.

For the item choice UI, I'm building an invaders-style screen with 3 stacked boxes centered on screen, using a full-width yellow banner on hover with a parallelogram sheen effect created via stencil masking. The title uses FatPixel with a wavy effect, flanked by two mirrored bobbing emojis, layered with hover and click sounds—all drawn directly with layer primitives rather than UI widgets.

The shop is a full-screen state with a grid of card tiles showing 6 passives plus a dagger weapon at 5-8 gold each. Gold displays with a cash-register kick animation, and affordability is shown via banner color (yellow if affordable, gray if not). Failed purchases trigger an error shake, red tint, and a cursor swap to a red X for 0.4 seconds. Successful buys play success sounds, spawn hit circles and coin particle effects with emoji. The "Next Wave" button is primary green, and item tooltips appear on hover.

For gold collection, enemies drop coins at 25% rate with physics (circle collider, 0.7 restitution, spinning upward 160-280 pixels). The player collects coins via sensor overlap, triggering collection sounds, a white ring effect, and counter updates. Coins only persist during the arena phase; at wave end, remaining coins vacuum toward the player with steering force before the item shop appears.

The HUD shows the health bar in the top-left corner alongside a gold label chip displaying the coin count. the lightning bolt itself as a simple visual effect—a few zap particles dropping fast, a bright white-yellow column flash for a frame or two, then impact sound and knockback on enemies plus damage to the player if they're caught in it. Enemy bullets are yellowish circles fired at the player with a trailing particle effect made from small shrinking circles spawned every few frames, and they damage on contact or disappear when hitting walls.

For collision damage, I'm handling player-enemy hits with a simple hurt state and knockback, gated by invincibility frames. The player's face swaps between a slight smile and a dizzy expression when hurt or landing hard, while enemies just flash white on impact—no need for per-enemy hit animations. I'm also implementing the wind plant system with four channels and damping decay, placing plant clusters across floors and platforms that react to player landings, bullets, muzzle blasts, and lightning strikes, with a few simplified plant archetypes in the 10-16 pixel range.

For the plant species, I'm cycling through seedling, sheaf, blossom, tulip, and four-leaf clover. The clouds are adapted from the demo version to fill the full-screen sky. The win/loss screens use overlay text with a retry button triggered by R or click, and the lost screen plays a death animation before wiping to the game over state. I'm extending the transition system to accept custom origin points—modifying transition.lua to let the wipe start from any screen coordinate rather than always the center, computing the radius needed to cover the entire screen from that point.

For the cursor, I'm adding a spawn effect and a brief error persona image swap on the game side. The sound system uses helper functions to pick random variations from a set, layer pairs of sounds together, and escalate pitch based on a counter. I'm keeping the finger cursor from the invaders game and leaving the sound tuning table empty for now. The F4 and F5 debug keys continue working through their existing update hooks.

For visual polish, I'm adding a screentone effect to the shop screen background using the cookbook recipe—a fade over flat color applied via effect_rectangle on the overlay layer. This showcases the effect system in a contained, testable space. The full file should land around 2000-2500 lines.

I need to verify the emoji/ui/init.lua contract (ui_begin and widget updates in the update loop) and confirm fx.lua's damage numbers work correctly with world-space positioning tied to the main camera. Then I'm setting up the physics tags and collision rules: player, enemy, wall, bullets, and coins, with appropriate collision handlers for hits and sensor-based collection.

For the sensor setup, I'm deciding whether coin collection uses a sensor, making player↔enemy a sensor to allow pass-through contact damage with i-frames instead of blocking movement, and enabling enemy↔enemy collisions with throttling to prevent stacking. The dagger projectile needs the player_bullet tag with some bounce off walls.

For the dagger specifically, I'm giving it gravity and restitution so it bounces realistically, then setting it to damage enemies on contact through a sensor (so it passes through rather than bouncing off them), with a hit-set to prevent multi-hitting the same enemy while overlapping, and it disappears after a few wall bounces or a timeout. The gun bullet is simpler — no gravity, travels straight, bounces twice max, and dies on the third wall hit or any enemy contact. I need to implement per-projectile hit-tracking to avoid the multi-hit problem.

For movement, I'm using a raycast downward from the player each frame to detect if they're grounded rather than relying on collision events. The player itself is a fixed box with no friction or restitution, and I'll set velocity directly for movement control like the classic Invaders style. World gravity needs to be defined, and I'm checking whether to use collision begin/end events or just the raycast approach for ground detection.

I'm settling on world gravity at 685 pixels per second squared, with different gravity scales for different entities — coins around 0.6, daggers 0.45, clouds and bullets at 0 so they're unaffected. The camera will stay static.

For the camera effects, I'm layering in hand camera movement, trauma-based shake, and punch feedback, with a rotation field that lerps smoothly and gets small roll adjustments from the player's horizontal velocity. The shake system adds rotation through its effects separately, so that works fine.

Ground and platforms are static box colliders tagged as walls, drawn as green outlined rectangles on the game layer. Plants will sink slightly into the ground through base offset positioning, and where they touch the ground layer, their outlines naturally merge together like in the original.

For draw order, I'm splitting plants into back and front layers — back plants render before player entities, front plants after, all on the same game layer so depth sorting handles it naturally. The item choice UI sits on the overlay layer with a translucent background, while banners and text go on the UI panels with wavy title effects using per-character sine wave offsets. I'm using the stencil mask API to handle the sheen effect — drawing the mask shape, enabling stencil testing, rendering the stenciled content, then disabling it.

For hitstop, I'm decrementing the timer each frame and zeroing out the scaled delta time when active, which pauses entity timers downstream. So the solution is to route hitstop through the slow_mo system itself: set slow_mo.scale to 0 when hitstop triggers, then use an unscaled timer to restore it after the duration. Since juice_timer uses scaled delta time it won't fire while frozen, so I need a separate unscaled game timer that ticks with raw dt to handle the restoration callback. This avoids conflicts with slow_time effects since they operate independently.

For the item particle system, I'm spawning emoji particles with specific physics (velocity 100-125 in random directions, scale 2.5, duration 0.5-0.6 seconds) and adding a tray pulse effect — either through the UI widget system or by drawing emojis directly with game-side springs and handling tooltips separately.

For the shop, I'm using UI card widgets with tooltips and a buy flow that checks gold; cards have count-aware descriptions, and most items stack after purchase except the dagger which shows as sold after the first buy. I'm skipping the wave timer and score system for now since that's specific to the game's progression mechanics.

Now mapping out the sound effects across all the game events—hop, landing impacts on different surfaces, player and enemy interactions, weapon effects, and environmental hazards—each with specific volume levels and some with pitch variations for variety. Shop interactions need ui_error for unaffordable items and ui_success for purchases, plus a neutral click sound. For crits, I'm layering dagger_crit1 and dagger_crit2 together like the invaders design intended. The ball_wall sound can stay in the toolkit even though the demo is gone — it's harmless to keep. I'm setting up the sfx function to take handle, volume, and pitch, with pitch already jittering 0.95-1.05 by default, and I'll write a game-side loader to pull sounds from the bank.

For toolkit changes, I'm adding origin point support to transition.lua and keeping everything else on the game side. The old demo is completely replaced — ball and target are gone, but I'm keeping the reset binding and implicit wipe usage in the flow. Now I need to inventory the asset sources across EBB, aimer, and invaders to find all the emoji and icon PNGs at 512px resolution. I'll prioritize copying assets from Invaders for authenticity since their 72px sources work fine for our smaller sprite sizes, and fall back to downloading missing emojis at 512px from Aimer or EBB's catalogs.

Now I'm inventorying all the assets across the three directories, then I'll copy everything over, extend the transition logic, write the main game file, integrate sound loading, run syntax checks, and update the documentation with test instructions.

I've confirmed the API and toolkit are set up. Now I'm inventorying the old games' asset folders to source authentic sprites for copying.

I'm checking what assets I have available across the three folders—the EBB set has weapons and nature elements, Aimer has objects and effects, and Invaders has the authentic pixel art sprites I need.

Now I'm planning the copy operation: pulling specific PNGs from each folder into the template's assets directory, then gathering all the sound files from the emoji bank plus a few extras from the invaders sounds. After that I'll need to update the transition.lua file to support origin positioning, then move on to writing the main game logic.

I should also verify the UI layer setup and check how the juice.lua module handles sound bindings—specifically what volume levels it uses for hover and pop effects, since those will now actually play with the real sound bank loaded.

All sprites are available across the three games without needing downloads. I'm checking the UI toolkit's sound hooks next, then copying the assets once the bank loads.

The UI kit expects `sounds.ui_hover` and `sounds.ui_pop`, but the sound bank only has `pop` instead of `ui_pop`. I'll map `sounds.ui_pop` to the bank's `pop.ogg` file so the UI/juice module can play both sounds at the appropriate pitches.

Now I need to copy the assets and sounds into place, update transition.lua, and then write out main.lua.

The UI kit needs `sounds.ui_hover` and `sounds.ui_pop`, which the bank has available with pop.ogg aliased. I'm copying the assets and sound bank now.

I've got the assets loaded—40 PNGs and 62 sound files with mixed resolution sources that work fine since the draw scale adjusts based on the target width. Now I'm updating transition.lua to support origin positioning, adding x and y fields that default to the screen center, and calculating the cover radius as the maximum distance from that origin to any corner plus a margin. Then I'll move on to updating main.lua.

For the contract phase recentering that Aimer needs, I'm going with a clean approach: store an optional origin function in the transition that gets called at both the expand and contract phase starts, letting the game pass in the current cursor or player position dynamically without overcomplicating the API.

Updating transition.lua now...

I've staged the game assets and now I'm implementing transition wipes that originate from a research-confirmed meaningful point instead of the hardcoded screen center.

The file E:\a327ex\emoji-template\emoji\transition.lua has been updated successfully. (file state is current in your context — no need to Read it back)

I'm planning out the main game file structure, starting with the header and imports, then setting up physics with collision tags for the player, enemies, bullets, and coins, followed by the camera system, input bindings, asset loading, sound management with helper functions, and the core game state tracking for waves and progression.

Now I'm laying out all the game entities and systems: plants with wind effects, clouds, solid platforms, coins, the three types of projectiles, three enemy types, spawn effects, the player with movement and combat mechanics, items with definitions and effects, the wave progression system, UI screens for item selection and the shop, the HUD display, and the main game flow functions that handle starting runs, clearing waves, and ending conditions.

I need to be careful with the physics API—colliders take an owner, tag, body type, and shape with optional sensor mode, and I'm checking the normal direction convention to make sure collision detection works correctly for things like floor contact and knockback.

For the player's grounded state, I can't rely solely on collision begin events since those only fire once; instead I'll use a raycast downward to persistently detect contact with solid platforms, which simplifies the jump and hop logic compared to tracking movement tokens. So the movement hop chains when holding a direction while grounded—each ground contact refreshes the available hop, triggering another one if the input stays held. Releasing stops horizontal velocity. For jumping, I need to track the initial jump height and cut the upward velocity to a lower value if the player releases while rising but after traveling more than 34 pixels; releasing earlier just lets them fall naturally without the cut. While airborne, the visual rotation increases based on direction.

For the physics setup, I'm keeping vertical velocity intact when updating horizontal velocity, setting the player collider as a box with no friction and fixed rotation, and tuning the weapon orbit radius to about 22 pixels at the 480×270 scale with rotation offsets for the gun and dagger based on their art direction.

For weapon aiming, I'm implementing the gun with a π radian offset and flipping it vertically when aiming left by checking the cosine of the aim angle, similar to how the original game handled it. The dagger uses a −3π/4 offset and spins when thrown.

For firing, I'm setting up a cooldown system that triggers while the mouse button is held, firing the weapon repeatedly at a set interval. Writing recoil animation... Writing telegraph animation... When the cloud splits on death, it spawns two smaller clouds at offset positions with a sound effect. The clown enemy hops randomly on the ground with 3 health, and when hit it teleports to a random location 40–80 units away from the player, playing a pitch-shifted sound and spawning particles at both the departure and arrival points. Enemy contact with the player deals 1 damage with knockback, and I'm setting flat health values across enemy types: aliens have 2 hp, big clouds 3, small clouds 1, and clowns 3, while weapons deal 1 damage for the gun and 2 for the dagger.

I'm settling on six items—fire, chili, melon, mushroom, coffee, and hotdog—without additional damage scaling items, and defining the enemy waves with increasing counts and variety: wave 1 has 4 aliens, wave 2 adds a clown, wave 3 introduces clouds, and later waves mix all three types with higher numbers. Enemies spawn every 0.6 seconds from a queue using the spawn effect.

For spawning mechanics, I'm randomizing the top position with grounded enemies falling in from y 40-60 while clouds spawn higher at y 40-70 and remain airborne. The spawn effect creates a growing circle that peaks to spawn the enemy with sound and a burst, then shrinks. Wave progression tracks when the spawn queue and enemy list are both empty to determine if the wave clears or if the player wins after wave 5, otherwise moving to item selection. On the final enemy kill, I'm triggering a reward slam that slows time, shakes the camera with trauma, and applies a camera punch for impact.

After the slam finishes, the arena clears with a sound effect and the item choice overlay appears—no wipe transition, just the overlay layered on top. The item choice state displays a translucent charcoal overlay with three boxes stacked vertically in the center, positioned and spaced to fit the screen height.

Each box responds to hover with a full-width yellow banner that animates in smoothly, accompanied by a parallelogram sheen effect, spring physics, and hover/click sounds. The item name displays in a wavy FatPixel font with two mirrored emoji icons (24px) that bob up and down in sync. When unhovered, the boxes show just the name and emojis in a smaller font without the banner. I'm handling hover detection based on mouse position within each box.

On click, I'm triggering multiple sound effects and spring animations before applying the item to the tray and navigating to the shop with a wipe transition from the cursor position. For the wavy title effect, I'm drawing each character individually using FatPixel font, calculating the x position by summing the width of each character as I go. I need to be careful with FatPixel's rendering scale—it renders at roughly 3x its nominal size, so I'm checking how it was used in the original Invaders implementation to match the visual style.

For the item titles, I'm switching to the mid-sized Awesome font for more predictable rendering, then applying a sine wave animation to each character's vertical offset with an amplitude of 2 to create the wavy effect. For the sheen on the banner, I'm using a stencil mask to define the banner's rounded rectangle shape, then drawing skewed parallelograms within that mask to create the moving highlight effect before rendering the text on top.

I'm uncertain about the stencil semantics — whether the mask shape itself renders visibly or stays invisible like in LÖVE — so I'm considering an alternative approach: drawing the darker yellow parallelograms first, then layering the banner rectangles on top, or manually clipping the parallelogram vertices to the banner bounds since it's a full-width rect and the clipping math is straightforward.

Actually, for a full-width banner band, the parallelograms with their fixed skew (±25 pixels) and vertices naturally contained within the band height don't need stenciling at all — the y-coordinates are already constrained by construction, and horizontally they fit fine. I'll draw the banner as a full-width yellow rectangle with four darker yellow parallelograms spaced across it, scaling them from the center during the animation.

For the shop state, I'm setting up a charcoal background with a screentone panel effect as the backdrop board. The ui_label widget draws at the specified y position with the kick offset applied. For the shop cards, I'm laying out a 4×2 grid of 7 cards (6 passives plus a dagger), each 48×48 with price banners that change color based on affordability. On hover, a tooltip shows the card description, price, and coin icon. When clicking a card, the game checks if the player has enough gold — if so, it deducts the cost, increments the stack, and triggers success feedback with a coin burst and ring effect at the cursor plus a slot pop animation. If the player can't afford it, an error shake plays on the card and a red flash appears over it.

For the error state when a purchase fails, I'm swapping the cursor image to an X mark for 0.4 seconds while playing an error sound, then restoring it — keeping it simple without rotation. The shop also displays item prices (fire 5, chili 5, melon 4, mushroom 6, coffee 5, hotdog 4, dagger 8) and includes a "Next Wave" button at the bottom that wipes from the cursor to start the next wave. The owned items tray appears in the same HUD area.

For buying mechanics, acquiring a dagger sets the flag and allows Q to swap weapons. Coins drop at 25% rate with a guaranteed 2 from clowns, and I'm starting the player with 4 gold so they can afford something after wave 1. At wave end, coins ignore gravity and steer toward the player using a seeking force at 300+ speed, collecting on contact; any remaining coins when the item choice screen opens get added directly to the gold total.

When the player takes damage, I'm checking if they have a melon charge active to consume it instead (with sound, particles, and 1 second of invulnerability), otherwise reducing HP and triggering slow-motion, screen shake, visual feedback like flashing and a dizzy face, plus a 2-second blink effect. If HP drops to zero, a mushroom revive restores 1 HP, otherwise the player dies with a burst effect and transitions to the lost screen after a delay.

For the end screens, I'm overlaying a charcoal background with the title and subtitle, then showing a RETRY or NEW RUN button that wipes and restarts the run by resetting all game state—clearing enemies, coins, projectiles, and effects while keeping plants and clouds as permanent dressing, and resetting the player's position, health, items, gold, and wave counter. The HUD displays health with a heart icon and gold/wave labels using UI widgets, with a custom tray for tooltips.

For the draw order, I'm rendering the charcoal background and sky gradient across the full screen with clouds, then camera-attaching to the game layer to draw solids, back plants, coins, enemies, the player, and front plants in sequence. Effects layer stays camera-attached for particle effects, while the HUD widgets queue themselves during the update phase so draw() only handles game rendering and emoji display.

The item-choice chrome needs to run in update since it's interactive and uses layered UI elements like banners and text, similar to how the wavy text works. For the player, I'm skipping the draw call during invulnerability blink phases. Physics-wise, I'm setting gravity to 685 for the player, then tuning gravity scales for different objects—coins at 0.6 to float nicely with 0.5 restitution, daggers at 0.4, aliens at 1, clouds at 0, and enemy bullets at 0.

Now I'm mapping out the collision system: regular collisions between the player and solids for walking and landing, enemies with solids, projectiles with solids, coins with solids, and enemy-to-enemy bumping. For sensor-based interactions, I need to detect overlaps between the player and enemies, player and enemy bullets, player and coins, plus enemies and player bullets. I'm checking whether the physics engine's sensor system requires both bodies to be sensors or if enabling sensors between specific tags handles the detection automatically.

For landing detection during the squash animation, I need to catch the collision event between player and solid when the normal points downward, but the velocity at contact is already resolved by physics. So I'll track the previous frame's vertical velocity and use that as the impact speed for the squash effect. For grounded detection, I'm considering a raycast approach.

The weapon system has a gun with a 0.5-second fire delay that shoots bullets as rounded rectangles with a small circular collision radius, traveling at 340 units per second with full restitution to bounce off walls up to three times before disappearing, and they deal damage on contact with enemies before being destroyed. For the dagger weapon, I'm setting up a thrown entity with physics—it's a small circle that falls with reduced gravity, bounces off surfaces with some restitution, and travels at high velocity toward the aim direction while spinning visually. It deals damage on contact with enemies using a per-enemy cooldown to prevent rapid multi-hits, and when it hits walls it triggers impact effects with sparks and a spring pop. After a few wall collisions or a timeout, the dagger becomes embedded and fades out with a blink animation before disappearing, plus I'm adding the throw sound effect.

Now for the chili item effect: when the dagger damages an enemy, there's a chance to trigger a chili proc that damages the nearest other enemy within range and spawns a chili-colored particle burst at that target. The fire item works similarly—on hit it can ignite an enemy for a few seconds, spawning fire particles continuously during the burn and playing a burn sound. For enemy death, I'm spawning a white ring and colored particles at the death location, with each enemy type having its own color palette.

For damage numbers, I'm spawning a blue "+X dmg" text at the hit location. Coin collection shows a gold-colored "+1" at the player. I need to load all the sound effects from the assets folder and set up a volumes table, plus create an alias so the UI pop sound references the same file.

UI interactions trigger hover sounds at reduced volume with pitch variation. The weapon draws at an offset from the player based on aim direction, with recoil affecting both rotation and position. Aiming comes from the mouse position converted to world coordinates relative to a fixed camera.

Plants are objects with position, image, size, and flip state that respond to wind forces applied periodically or from impacts like bullets and lightning strikes, spawning in clusters across the level.

For plant physics, I'm calculating wind as a combination of constant sinusoidal wind based on position and time, plus occasional random wind streams that accelerate the rotation velocity over a couple seconds, with moving plants having their own momentum acceleration separate from direct forces, all decaying smoothly using a damping function that reduces values to 10% over one second.

Now I'm implementing the plant's moving force handler...

Instead of using timers for each plant, I'll track when the movement should stop with a simple time comparison. The update loop applies acceleration to the moving velocity while it's active, caps it, then applies damping to both the velocity and rotation to create that settling effect. The direct channel uses higher acceleration and a larger cap for more dramatic movement.

For the gust effect, each plant gets a staggered onset based on its index so the wind doesn't hit everything at once. While the gust is active, I'm adding random-scaled acceleration to the velocity and updating the rotation. The angle combines contributions from the stream, moving, and direct channels, and plants pivot at their base rather than their center, so I'm offsetting the draw position accordingly. I'm also handling flipping by adjusting the scale. I'm starting to organize plants into clusters with different species and sizes.

Now I'm laying out the solid platforms: a floor spanning the full width at y=240, off-screen walls to keep the player contained, and a few floating platforms at different heights to create the level structure.

Setting up the visual elements—green-colored solids with plants decorating the floor and platforms, clouds drifting in the background, and positioning the HUD with health bar and gold counter in the top-left, wave indicator nearby, and the item tray at the bottom-left with small spaced icons.

The item choice UI displays three boxes vertically centered with titles and mirrored emojis flanking them, and I need to make sure the player can't fire while these menus are active. Also handling the camera rotation with angle interpolation.

For the hard-landing impact, I'm applying a directional camera shake using a spring impulse pointing downward, with the intensity scaling based on the landing velocity.

Now I'm setting up the trauma amplitude defaults — the camera shake system uses an amplitude vector with x, y, and rotation components, and the actual shake amount gets scaled by the square of the trauma value. Looking at the demo, small hits use around 0.2 trauma, enemy deaths around 0.35, player damage 0.5, and critical hits with rotation-only effects at 1.0.

I'm also adding the wave counter display and starting to define the item system with properties like name, description, price, color, and image. Then I need to implement the burn effect for enemies.

Setting up the burn mechanic where enemies track remaining burn duration and apply damage over time at intervals, spawning small fire particles while burning. I'm using shared damage functions across all enemy types since there's no class inheritance, so I'll write helper functions that work with any enemy object and maintain a central enemies list.

Now I'm deciding on the control binds — mapping multiple keys to the same action like left arrow and A for movement, W/up/space for jumping, and mouse click for firing, with Q for swapping weapons.

I need to set up the game state transitions: player death moves to a 'lost' state, winning happens after clearing wave 5 which triggers an arena clear and transitions to 'won'. Item selection appears as an overlay without a screen wipe, but moving from shop back to arena uses a wipe. Input should only register when the player is in the arena, and restarting a run clears all enemies and their lists.

Writing the main file now...

I'm verifying the API calls as I go: gradient rectangles, spring physics, timer tweens and callbacks, circle colliders with sensor options, raycasts, and circular entity queries all check out against the documentation.

Continuing through the remaining functions: shake push for physics, camera mouse handling, UI cards with interaction states, tooltip positioning, buttons with click detection, labels with icons, HUD bars with values, and effect rectangles for visual feedback.

Now I need to verify the exact signatures for the effect functions—rectangle, circle, rounded rectangle, and image—by checking the effect.lua file. I should also confirm that color tokens like 'blue' work as string names in the spec, verify the sfx function takes volume and pitch in the right order, and check how flash colors work with layer_image, particularly for telegraph effects using color mixing.

365:function effect_setup(opts)
366-  opts = opts or {}
367-  local path = opts.draw_shader or 'assets/draw_shader.frag'
--
451:function effect_set(layer, spec)
452-  spec = spec or {}
453-  local p  = pattern_kinds[spec.pattern or 'solid'] or 2
--
516:function effect_clear(layer)
517-  layer_shader_set_int(layer, effect_draw_shader, 'u_pattern_kind', 2)  -- solid
518-  layer_shader_set_int(layer, effect_draw_shader, 'u_color_kind',   0)  -- none (passthrough)
--
568:function effect_rectangle(layer, x, y, w, h, spec)
569-  effect_set(layer, spec)
570-  layer_rectangle(layer, x, y, w, h, 0xFFFFFFFF)
--
578:function effect_rounded_rectangle(layer, x, y, w, h, rad, spec)
579-  effect_set(layer, spec)
580-  layer_rounded_rectangle(layer, x, y, w, h, rad, 0xFFFFFFFF)
--
584:function effect_circle(layer, x, y, r, spec)
585-  effect_set(layer, spec)
586-  layer_circle(layer, x, y, r, 0xFFFFFFFF)
--
593:function effect_image(layer, img, x, y, w, h, spec)
594-  effect_set(layer, spec)
595-  local sc = math.min(w / img.width, h / img.height)

Now I'm ready to write the main game file systematically. I need to be careful about how effect operations work per-layer — the overlay layer has its own shader state, and effect brackets apply within that layer's rendering context, so I need to think through the ordering when drawing the shop backdrop and clearing effects alongside other overlay elements.

One key thing: effect operations and layer shader calls are queued and execute inside layer_render, so my sequence of effect_set → draw → effect_clear will work correctly. Also, I should rename the enemy cloud class to avoid conflicting with the dressing clouds list — I'll call it `storm` internally and maybe tint the sprite gray to differentiate it visually from the decorative clouds.

Now I'm setting up the physics collision and sensor matrix — defining which object types collide with solids, which ones trigger sensors for the player, and handling things like coins collecting, enemy contact, and bullet interactions with both enemies and obstacles.

The update loop follows a specific order: drain queues first, then process the destroy queue, then handle new spawns from input. I'm also managing two timers — a scaled game timer for normal gameplay and an unscaled timer for things like hitstop recovery and UI delays during slow-motion.

The state machine tracks five states: arena, item_choice, shop, won, and lost, with a brief wave_end micro-state that lasts 1.2 seconds between the last enemy kill and the item choice screen. When enemies contact the player, the sensor triggers a hurt function.

Enemy bullets are small circles with a trail effect that damage the player on contact. The clown teleports away when it takes damage and survives. A reward-slam triggers when all enemies are dead, the spawn queue is empty, and the wave is active.

Defining the wave progression with enemy counts across five waves...

Now I'm being careful about matching all the spawn effect signatures, making sure entities have timers before using flash effects since the hit feedback relies on timer callbacks, and properly cleaning up dead entities from lists. The cursor has a pulse effect, and the player blinks during invulnerability by skipping draw frames on an alternating pattern.

For the UI, I'm measuring text width with the mid font, creating wavy title characters by iterating through each character and accumulating positions, and animating the item-choice banner with per-box tweens that scale it in smoothly on hover and out quickly on exit.

Now I'm scaling the banner from its center point and adding a parallelogram sheen effect within the banner's height using a darker shade of the banner color. The item name displays as wavy white text on the banner with mirrored emoji graphics scaled horizontally. The item-choice screen is fully custom chrome rather than using widgets, while the shop screen uses widget elements and draws its own background behind the arena.

The game world pauses during non-arena states, only updating when in the arena or wave-end phases while effects continue animating. Gold display tweens smoothly with a cubic easing curve and bounces with a vertical kick animation. When purchasing coins, I'm spawning a burst of coin emoji particles in the upper hemisphere above the card with a yellow ring effect and success feedback. The card banner displays the price as a string with color-coding based on affordability, and the tooltip shows the item name as the title, the next stack effect as the description, and the price as the value.

For the tray, I'm drawing 22-pixel emoji icons with a small white count badge positioned at the corner on the UI layer, and hovering triggers a tooltip with a pulsing cursor effect. Now I'm writing the implementation file, keeping in mind the Lua 5.4 formatting gotcha where I need to use `%d` only for integers and apply `math.floor` to the displayed gold value since it's a float. I'll follow the operator spacing convention of tight spacing around multiplication and division, and spaced operators around addition and subtraction.

The file E:\a327ex\emoji-template\main.lua has been updated successfully. (file state is current in your context — no need to Read it back)

I need to verify the syntax with Lua and check a potential issue with the random selection function. The `random_choices` function might return duplicates, which could be problematic when picking items. To ensure unique selections, I'll swap to a shuffle-and-take approach instead — copying the item pool, shuffling it, and grabbing the first three elements.

Now I'm working through the remaining risky points: confirming that `table.copy` exists for safety, verifying the weighted random selection returns an index correctly, checking that array deletion by value works as expected, and validating that the layer parameters are properly supported across spawn functions. I'm also tracing through the draw order to make sure shop particles and effects render to the correct layers without camera interference. For input handling, the axis function should return -1, 0, or 1 as expected. The player hop mechanic needs careful attention — maintaining horizontal velocity while airborne and after landing requires the right state management.

There's a subtle edge case where the player is grounded but the jump token hasn't been restored yet, which means no velocity maintenance branch triggers and the player might decelerate unexpectedly. I'm refining the input release logic to only zero out velocity when no directional input remains held, rather than zeroing on any release event.

The jump height calculation uses the difference between jump origin and current y position since y decreases upward. For the rotation snap, I'm tweening to the nearest 2π multiple then resetting to zero, which avoids any visible jump since those orientations are identical. The hit effect and lightning column are being added to the effects collection properly so they update and draw each frame.

I notice the spawn_marker is going into the spawners list which only updates during arena mode, but I'm not drawing spawners in the main draw loop — I need to add that. Enemy bullets spawn hit circles as trails every 0.03 seconds into the effects layer. Now I'm checking the restart_run function which kills entities and processes the destroy queue.

The issue is that restart_run gets called mid-frame inside a transition callback, which happens before collision drains finish. If I destroy colliders there, the collision system might try to read events referencing bodies that are already freed. Instead of killing immediately, I should set a pending_restart flag that executes after the destroy queue processes at the end of update, same approach for state changes like opening the shop.

For the wave_cleared logic, there's a timing problem with the alive_enemy_count check — when an enemy dies, it's marked as _dying but not _dead until the destroy queue runs, so the count might still include the dying enemy and miss the wave-end condition.

But the storm split ordering actually works out: when a big cloud dies, its on_die spawns the two smaller clouds before the wave check happens, so the alive count includes them and correctly prevents a false wave clear.

I'm also verifying the weapon purchase system sets the current weapon correctly, the font text_width method syntax is right, and the UI text in the shop uses the correct font parameter.

For the color mixing, `color_mix` returns a color function that gets called with the packed arguments, and both `black` and `white` are palette globals. The layer_image function accepts color and flash parameters correctly, and the storm draw passes the storm color as both the color and flash arguments.

I'm checking the math utilities: `lerp_angle` takes a time parameter and source/destination angles, `shake_push` takes the shake object, angle, and amount with optional frequency and bounce parameters, and `timer_get_time_left` returns either a number or nil, which works as a truthy check.

Now I'm realizing the hitstop logic has some redundancy — when hitstop is active, I'm setting `sdt = 0`, but `juice_update` already ran with `slow_mo.scale = 0`, which means `dt` is already zeroed out. The extra check is redundant but harmless since `juice_update` calls `set_time_scale(0)` to freeze the engine and physics. The real concern is whether setting `slow_mo.scale = 0` actually freezes the physics engine properly, and if `slow_time()` gets called during hitstop, it could overwrite that state.

For the hitstop restoration, I'm using an unscaled timer that updates with raw `dt` to trigger the restore callback, which should work correctly. But I'm noticing something odd with the plant's draw offset — it looks like the image is being positioned at `(0, -image.width/2 + 2/scale)`, which seems wrong if the offset should be calculated in local pre-scale units.

Actually, working through the math: when I push the scale, the coordinate space gets multiplied by that scale factor. Drawing the image at `(0, -image.width/2)` in that scaled space translates to a screen offset of `-image.width/2 * scale`, which equals `-size/2` — exactly what I want to center the sprite `size/2` above the pivot. The `+ 2/scale` adds a 2-pixel downward offset on screen for the base sink effect, so the math checks out. The issue is that I'm passing `surface_y + 1` as the y-coordinate for the plant.

Now I'm verifying the rest of the implementation details: the plant scale flip uses a negative sx value to flip correctly, the enemy HP bar references the hitfx spring position which was properly initialized, the coin collection uses the medal_gold palette entry that's defined, and the alien class can reference enemy_bullet even though it's defined later in the file since Lua resolves globals at runtime.

For the wave spawner, the timer_every call passes the spawn queue length as the times parameter so it spawns exactly that many enemies, with the callback popping from the queue and a guard condition providing double safety against over-spawning. Item selection is switching to a unique shuffle approach, and the UI text rendering for item choices is being positioned correctly with the appropriate layer and font metrics.

The shop layout arranges cards in rows of four using modulo logic, and I'm working through the layer rendering order — drawing the background rectangle before applying the overlay effect, which queues the shader state changes in the correct sequence so subsequent overlay draws in other states aren't affected.

The HUD appears correctly in item_choice since ui_content composites above the overlay layer per the pipeline order, and the end_screen buttons reuse the same id for both win/loss states since they're not simultaneous. I'm also checking minor details like whether the camera resets on restart and tweaking the jump sound with a slight pitch variation.

For the cursor, the image_scale field is properly defined in the cursor class. I need to add spawner drawing in the main draw loop within the camera_attach block alongside the effects, and I'm verifying that melon_charge gets set correctly when waves start or items are given. The player hurt logic is already guarded by game state checks so damage can't occur during item_choice or shop phases.

Enemy timers pause correctly when the world isn't running. For the storm bob behavior, the velocity calculation uses proportional control to make the y-position converge toward home_y plus a sinusoidal offset — the current gain of 1 converges slowly over about a second, which is fine. The alien sprite dimensions are close enough to the collision box. I'm checking whether restart_run properly cancels the ambient_gust timer.

The wave_spawner timer gets cancelled on restart. Input axis returns a normalized value between -1 and 1 from keyboard input. Fire suppression is gated behind a game state check for the arena. The transition origin function can safely access the cursor since it exists by that point. The tooltip positioning function handles the case where options haven't been fully initialized yet. Array shuffle operates in-place and optionally takes a custom RNG.

Now checking the bullet wall-hit behavior — when bullets hit walls, they push nearby plants with a force calculation based on position and direction, which is a cheap approximation of the passing-through effect. Spawn markers are created as entities and only need update and dead checks in the collection. I need to add the missing draw call for spawners, fix the release velocity guard, replace random_choices with a unique shuffle, and defer the restart through a queue. The player death also schedules a transition via the game timer with slow-time recovery scaling.

For damage, the dagger has a hit_times field that enemy_take_damage checks, while gun bullets don't trigger that path. Sensor collisions only fire on enter, so a dagger sitting on an enemy won't re-trigger after cooldown since there's no repeat event while overlapped — acceptable since bounces move it anyway. Lightning columns in effects update even when the world isn't running. There's a minor edge case where reward_slam could fire if the last enemy dies while the player simultaneously dies. In the HUD update, I'm layering the tray icons onto the content layer.

The UI label options use a fill parameter that works in the gallery. I'll apply the four fixes through the editor and then run a syntax check.

I'm now doing a correctness pass to fix four issues I found: spawn markers not being drawn, vx incorrectly zeroing when releasing a key, potential duplicates in random_choices, and restart timing that could destroy Box2D bodies mid-drain.

I'm working through the restart deferral logic. The restart_run function gets called from several places—the transition callbacks for the R key, end screens, and player death—but these callbacks fire during transition_update, which happens before collision handling. To defer the restart safely, I'm planning to set a queue_restart flag in those callbacks instead, then handle the actual restart at the end of the update cycle.

SYNTAX-OK

I'm doing a careful review of the main.lua file to catch any logic issues. Checking the `player:update` method and its input handling, plus auditing the `enemy_take_damage` recursion to make sure the proc callback doesn't create infinite loops.

Looking through the item mechanics — the fire stack chance calculation matches the description (25% base + 10% per stack), and the UI elements like the HUD bar and item choice tooltips are wired up correctly. The draw order is right with the sky gradient covering the full screen, and lightning strikes only trigger during arena mode as intended.

For the storm mechanics, the charge tween pauses when enemies stop updating outside the arena, which prevents damage after transitioning to item_choice. The alien shoot timer uses a fixed random delay rolled once per loop, and the collision sensor pairs are registered consistently with the physics setup.

Checking the spawn marker—it only adds enemies while in the arena, so no spawning happens during pause. When the wave clears, the game transitions to 'won' state safely without destroying bodies, and the won screen shows an empty enemy list with the arena frozen behind the overlay. The slow motion scale might be mid-recovery on restart, but that's fine since the juice timer continues ticking with scaled delta time. Also confirming the snap function works as expected.

Now verifying some utility details: fonts have a height property, ui_text is available from the gallery, and timer_every with a times argument stops after firing that many times. The tricky part is enemy spawning during collection updates—when enemies split from storm effects during the burn tick inside the update loop, they're being appended to the same list that's currently being iterated over.

I'm not sure exactly how collection_update handles mid-iteration appends, but to be safe I should defer the storm split spawning using a timer with a small delay like 0.01 seconds, which fires after the current frame's timer updates complete. That way the new enemies spawn cleanly without interfering with the active iteration.

Now checking the remaining details: plants rustle when the player hops through them, the dagger rotation uses a flip offset, the gun flips vertically when aiming left, the item tray stores hover state on the spring table, and ui_label returns are ignored as expected.

Verifying the screen update formats the wave count correctly, the item choice prevents double-clicks, the shop marks weapons as sold after purchase, coin collection during vacuum works despite overlap issues, aliens and clowns get squash spring effects on hit, text layers use dark foreground colors, and the wave label display is set up.

I should also confirm that `effect_rectangle` uses valid palette token names like 'blue' that match what's defined in effect.lua, and that the widget ordering within the update function works correctly since they're called after the destroy queue processes. The cursor error timer is using the unscaled timer with the right name, and once the storm split fix is complete, I'll do a final check, update the documentation, and write up test instructions.

Now I need to update CLAUDE.md since main.lua is no longer just a demo scene but the actual showcase game — I'll revise the Layout section and add a note about the reference and research materials, keeping the documentation edit brief.

The file E:\a327ex\emoji-template\main.lua has been updated successfully. (file state is current in your context — no need to Read it back)

I'm spotting a timing issue with the deferred split and wave-end check: when the big storm dies, it schedules a split for +0.02 seconds, but the wave check runs immediately after and sees the spawn queue as empty with only one alive enemy (itself), so it marks the wave as cleared and triggers the reward. Then the two small clouds spawn right after, creating a state where the wave is marked cleared but enemies are still alive. The deferral is introducing this bug, so I need to rethink the fix.

The solution is to track pending splits with a counter that increments when on_die schedules a split and decrements when those splits actually spawn. The wave-end check then requires this pending counter to be zero before declaring the wave cleared. This way, whether the splits spawn before or after the check, the counter ensures we don't prematurely end the wave. It also restores the original behavior where on_die ran before the check, accounting for splits in the alive count.

I found that the deferral breaks the wave-end check because splits aren't counted when the parent dies, so I'm adding a pending counter to fix this gap.

I should wrap up with a summary and testing instructions, making sure to flag any areas I couldn't fully verify without actually running the code.

I need to check the actual alien movement code from the reference implementation instead of assuming they hop—they should be floating around like in the original super emoji invaders. Let me look at the alien behavior section in the source to copy the correct movement pattern.

For the gun angle issue, the problem is that the gun art points left by default, so I need to add a π offset to the rotation to make it point in the correct direction. When aiming right, the gun ends up upside down, which is why I need to apply a vertical flip based on the aim direction—specifically flipping when the cosine of the aim angle is positive.

Rather than trying to figure out the exact flip logic myself, I should look at how the invaders game handles the same gun sprite and copy its rotation and flip math directly from that code.

For the jumping inconsistency, the issue is that the raycast for detecting ground contact extends 12 pixels below the player's center, which is about 4.5 pixels below the feet. When the player hops with an upward velocity of 90 pixels per second, they leave that raycast zone in roughly 0.05 seconds, which should be fine. The real problem seems to be something else with the jump logic. So the movement hop fires first when holding a direction, consuming the token and setting vy to -90, then if jump is pressed that same frame it overrides to -300 — that's working as intended. The real issue might be in the jump release logic, which checks if the jump button was released while jumping and applies cut velocity based on how high you've climbed since the initial press.

The actual inconsistency is probably that during normal walking with the hop chain, the player spends roughly half their time airborne from those micro-hops, so jump presses frequently miss the grounded window entirely. That's why it feels so unreliable compared to something like Invaders, which uses a jump token system that persists until you make contact with a static surface. ump allowed when jump_token is true, regardless of raycast grounding — that way jumping during hop chains stays reliable. For the bullet collision issue, I'm wondering if the sensor setup is wrong. I used `physics_enable_sensor` with `sensor_entities_begin`, but maybe the engine needs one of the tags created with `{sensor=true}`, or perhaps I should be using `physics_enable_hit` instead for solid-ish overlap reporting without collision response.

Let me check the framework's physics.lua and the arena example to see how bullet-enemy hits are actually implemented there, and look at the API docs to understand the three pair modes: collision (physical + events), sensor (sensor events), and hit (overlap detection with approach speed).

The player sprite vanishing while falling might be tied to the invulnerability blink timer that gets set during the jump — I need to trace when `invuln_until` is actually being set and whether it's persisting longer than expected during the fall state. %) % 2 == 1` handles the invulnerability blinking, which starts at -1 so that's not the issue. The rotation snap tween during landing animates the visual rotation back to zero, and during the fall the air_spinning flag keeps visual_r growing — neither would cause the sprite to vanish. Maybe it's a camera or layer issue?

Actually, I'm wondering if the direction multiplier could be zero somehow — the sprite rendering uses `self.direction * sx` for the horizontal scale, and direction only gets set when there's input, defaulting to 1. Unless the spring for the hit effect pulls sx to zero, but that's only 0.15 on fire. Let me think about whether the jump-cut could be zeroing something out, or if there's a temporary rendering issue I'm missing.

Wait — I found it! The dizzy image is 72 pixels, but it's being scaled using the same scale factor as the main sprite (18/512 from the slight_smile image width), which makes the dizzy face draw at only about 2.5 pixels — basically invisible. The dizzy effect triggers on hard landings after a jump exceeds 200 velocity and shows for 0.2 seconds, which matches exactly when the sprite disappears. I need to give the dizzy image its own proper scale instead of reusing the main sprite's scale.

Checking the rest of the codebase for similar scaling issues — alien, clown, and the item sprites all compute their scales correctly from their own image widths, and the UI elements handle scaling properly too. Dizzy was the only place mixing scales incorrectly.

Now I'm looking at the sensor system for the bullet collision issue and need to understand how the physics framework handles sensor semantics, then check the alien behavior code.

Looking at the alien invader behavior, they're steerable floaters with no gravity that use a combination of steering forces—they arrive toward the player within a certain range, maintain a minimum altitude, separate from other enemies and players, and wander around. They orient themselves to face the player and render with a rotation offset.

Now I'm realizing the core issue: sensor events in Box2D require at least one shape to actually be marked as a sensor, but in the current setup no shapes have that flag enabled. The framework's `physics_enable_sensor` just activates event collection, but the shapes themselves need `{sensor = true}` in their options. The problem is that making bullets sensors would prevent them from bouncing off walls since sensor shapes don't participate in physical collisions. I'm considering whether to use the alternative `physics_enable_hit` and `hit_entities` functions instead, which might handle collision detection differently.

I found that the invader alien uses steering behaviors with arrive, wander, and separation, and I've identified the sensor bug—events need an actual sensor shape. Let me verify the contract in physics.lua and the arena example.

9   
10    The normalization matters because the engine's `tags_match` is order-
11    insensitive, so a query like `collision_entities_begin('player', 'enemy')`
12    could receive events where the collision was recorded as
13    `tag_a='enemy', tag_b='player'`. Without normalization, you'd get `ev.a`

So sensor events only fire when both the shape is marked as a sensor AND the physics system has that sensor pair registered. Since my bullets, enemies, coins, and players are all regular colliders, I'm getting zero sensor events—I need to decide whether to convert bullets to sensors or handle collisions differently for the game mechanics I want. with player contact, I need to decide which shapes are sensors and which aren't. Enemy bullets should be pure sensors since they don't bounce off walls—they just die on contact. If I mark ebullet as a sensor shape and enable sensor events for both the solid walls and the player, the collision system will fire events appropriately: ebullet touching a wall triggers a sensor event to destroy it, and ebullet touching the player does the same. The key is understanding that sensor shapes generate events for any enabled pair, regardless of whether the other shape is physical or not.

For gun bullets, though, I need both wall bouncing and enemy detection, so I'll use a physical main shape for the bounce physics plus a sensor sub-shape specifically for enemy overlap detection.

Actually, the simpler approach is just enabling collision between the bullet and enemy directly — the gun bullet dies on impact while the dagger bounces off naturally with a per-enemy cooldown to prevent rapid re-hits. The mass difference is small enough that the knockback feels fine. Enemy bullets hitting the player would also cause a tiny shove, which is acceptable given the low mass involved.

For player-enemy contact, I'm treating it as physical collision too — enemies like clowns that hop into you should deal damage on contact, which matches the arcade feel of those games. The floating aliens maintain distance so they rarely touch anyway. I'll enable collision between player and enemy, trigger the hurt event on contact, and let the i-frames and knockback impulse handle the rest.

For coins, collecting them on collision-begin and immediately removing them avoids any physics response — the one-frame physical interaction before the coin dies is negligible. So I'm switching everything to use collision pairs instead of sensors, relying on collision_entities_begin events which I know work from the ball-wall demo. This means removing all the sensor registrations and handling everything through collision events, then tuning restitution and mass values for things like bullet behavior.

For specific interactions: daggers bounce off enemies (restitution 0.65) and don't re-hit on the same frame, coins are always collected on touch, and enemies get physically shoved by the player unless they're floaters that override velocity each frame. Now I'm looking at the alien steering methods available in the collider class — arrive, wander, and separate functions with their respective parameters.

For the invaders specifically, I'm setting max speed to 75 and max force to 1000, then implementing a boundary constraint to keep them in the upper half of the arena by applying a strong upward force (around 800 units) when they drift below the y-limit, similar to how the original weighted the steering forces.

I'm also clamping velocity to the max speed, setting rotation to face the player with the appropriate offset for how the sprite is drawn, disabling gravity entirely, and applying linear damping for smooth movement. The separation steering needs access to the enemies list to avoid clustering, and I'm keeping the shoot timer and telegraph system while adjusting bullet spawn positions.

Now I need to check whether the clown enemy should also use the floater behavior from the invaders version, since it likely extends the same enemy base class. Let me review more of the invaders code to see how clown and cloud movement work, plus the gun angle calculations.

For the jump mechanic, I should restructure it with a jump token system where `can_jump` gets consumed when jumping and restored only on ground contact. This matches invaders' `jumps_left` semantics — the jump triggers when pressed if `jumps_left >= 1`, regardless of whether the player is already airborne from a movement hop, and the counter resets whenever there's static contact with the ground.

The movement hop fires when grounded with the movement jump input, so if the player's holding a direction while landing, the hop triggers on that same frame, creating a continuous chain. If they press jump while rising from a hop, `can_jump` allows it to work seamlessly.

For the dizzy sprite, I'm scaling it at draw time using a spring-based calculation relative to the image width. Now I need to check the invaders code sections for the clown, cloud, bullets, and gun behavior.

I found the issue — shapes need the sensor flag set to true for hit events to register. I'm switching to collision events instead and now reviewing the enemy roster and gun math to replicate the existing behavior and weapon orientation.

I'm looking at how the gun rotation works in the invaders code—it stores the aim angle, calculates which direction the sprite should face, then adjusts the visual rotation accordingly and flips the sprite horizontally when aiming left.

But I'm realizing there's a mismatch with the actual gun art: the twemoji pistol points left, so if I'm using the invaders math directly without accounting for that, the gun would appear backwards when aiming right. Either invaders uses a custom gun sprite that points right, or there's something about the angle calculation I'm missing.

The safest approach is to just copy invaders' 72px gun asset and their exact math—including the dagger offset of `aim − 3π/4`—since that's known to work, rather than trying to adapt EBB's 512px version which has different rotation and flip conventions. options: invaders' proven gun asset and math (rotation = aim, with direction-based flipping), or keep EBB's approach (rotation offset by π with y-flip). I'll go with invaders' gun file since I'm already using their alien behavior and the math is battle-tested. For the dagger, I can keep my 512px version since it's the same twemoji art that EBB used with the −3π/4 offset.

For muzzle positioning, I'm adapting invaders' formula to compute the barrel tip offset perpendicular to the gun's aim direction, then firing bullets along that same aim vector. Their recoil uses a rotation kick with perpendicular offsets based on the visual rotation, plus a quick cubic easing in and slower linear recovery — I'll apply that same pattern to mine.

Now for the clown: it's a floater type that arrives, separates, and wanders with a max velocity of 75, always facing the player. When hit, it teleports to a new position 40–80 units away at an angle offset from the player, maintaining 30 units of clearance from other enemies and staying within the vertical bounds. Contact damage pushes the player upward with an impulse that decays over half a second. I'll convert my clown to use these exact floater behaviors, handling the push impulse by adding velocity and letting it decay naturally.

The cloud is a horizontal flyer with a fixed velocity — invaders set it to 50 for the larger variant...

Defining cloud behaviors... I need to refine the split logic so it triggers at the half-health threshold rather than on death — checking `can_split and hp <= floor(max_hp/2)` in the `on_survived_hit` callback ensures the cloud splits when damaged down to half health, spawning two smaller clouds, while direct lethal damage that reaches zero hp just kills it outright without triggering the split. Writing the after_damage hook... Setting up the cloud enemy's attack pattern with a cooldown-based strike when the player gets close, and handling the clown floater's gravity-free movement with steering toward the player and contact damage. Now refactoring collision versus sensor detection for player-enemy interactions to properly handle damage and i-frame throttling. The dagger bounce off enemies works fine, and enemy bullets pushing the player slightly on hit is acceptable knockback. Coins bouncing off the player before collection is also fine. Physical contact between enemies and the player is brief and acceptable—they can briefly stand on or block the player, which matches the original invaders setup. For the jump mechanic, I'm restoring the grounded raycast check to set can_jump to true, then only allowing jumps when the input is pressed and can_jump is true, immediately setting it to false after jumping.

The tricky part is that the raycast extends 4.5 pixels below the feet, and with the player rising at 300 pixels per second after a jump, they leave ground range in about 1-2 frames—which means can_jump might get restored while still rising. To be safer, I'm adding a velocity check so can_jump only restores when grounded AND the vertical velocity is greater than or equal to -10, preventing restoration during the upward hop.

For the dizzy effect, I'm scaling the image based on the ratio of 18 to the image width. I also need to grab the gun asset from the invaders game and check if there's a dagger image to use. For the alien, I'm rotating it by subtracting π/2 to face the player, and setting up contact damage.

Aliens should stay in the upper area by spawning above the midpoint and using an upward force to keep them there. For steering behaviors, I'm implementing arrive, separate, and wander functions with parameters for distance, radius, jitter, max speed, and max force — though I need to reconcile how the invaders' wander call maps to the steering system's signature.

For separation, I'll pass the enemies list to keep aliens apart from each other, and handle player separation separately. I'm settling on a max velocity of 75 and max force around 900 to give responsive but not overly snappy movement, with velocity clamped after force application.

Combining steering behaviors... Adding clown teleport mechanics... Adjusting bullet speeds and damage mechanics — aliens fire at 14-16 px/s while mine use 340 px/s at our scale, and I'm refactoring the weapon draw logic to handle directional flipping like the invaders version does.

Writing recoil animation... Now I'm going through the collision system changes: swapping sensor registrations for actual collision pairs, updating the entity begin callbacks, and rewriting the floater behavior for aliens and clowns. For the storm enemy, I'm keeping the simpler bounds-checking approach for direction flips instead of relying on collision events, and I need to handle the strike gate triggering when the player is below it. I'm also splitting the storm on low health using an after-damage hook, and starting to add logic to the enemy damage handler.

For the player, I need to implement jump tokens, weapon drawing in the invaders style, tween fields for actions, muzzle positioning, and fix the dizzy scale. I'll copy the gun sprite from invaders and update the collision event handler naming since sensors are now collisions.

I should also clean up the unused alien hop methods and be careful with the edit strings to ensure uniqueness when making these wholesale rewrites.

I found the issue: sensor events require `{sensor = true}` shapes, but mine were all physical, so they never fired. I've also got the exact math for gun orientation, alien steering, and cloud patrol behavior from the arena example, so now I'm applying these fixes starting with the asset and physics setup.

Checking spawn positions for floaters and storm constructors—aliens and clowns spawn between y 50–90, which is above the float line threshold, and clouds use the storm constructor with default direction settings. The spawn marker for clouds locks the y position between 40–85, and I'm verifying the coin vacuum behavior.

Coins now collide with the player physically before being collected, with both the vacuum distance check and collision event working together. The storm draw function doesn't reference the removed phase property—it only uses charge_t, spring, scale, and flashing, all of which are still present. Player-enemy collisions now make floaters solid, with aliens floating above and clowns bumping into the player; the i-frame system gates repeated contact events so collision begin only triggers on re-contact.

The enemy velocity is clamped at 75 with similar masses, so the physical shove is moderate plus my knockback impulse. The floater steering safely guards against a dead p1 reference using a fallback to screen center, and the steering separation function handles the enemies list even if it contains dead entries mid-frame.

There's a potential issue with floater_steering being called from alien:update during collection_update—it passes the same enemies list to steering_separate, which could include self at distance zero and cause division by zero. The arena game's invaders presumably handled this with self-exclusion, and Anchor2's steering_separate likely skips self internally, so the risk seems acceptable but worth verifying. The can_jump restore condition uses vy from get_velocity at the top of update, which is defined. Storm strike gating references game_state with start_strike properly guarded.

Aliens have restitution 1 for nice bouncing collisions with the player, and gun bullets fired from the muzzle might spawn inside walls when the player's close to one, which triggers an immediate wall event—that's fine. I should double-check the steering_separate implementation in collider.lua to confirm self-exclusion.

234:function collider:steering_separate(rs, others, max_speed, max_force, spatial_hash)
235-  local dx, dy, n = 0, 0, 0
236-  local px, py = self.owner.x, self.owner.y

Checking that the self-exclusion logic works correctly and the list entries have all required properties. Going through the syntax and making sure function definitions are in the right order — `floater_steering` is defined before it's used by the clown, and `FLOAT_LINE_Y` properly references the defined variable. Need to do one more pass on the storm drawing logic.

SYNTAX-OK

I've resolved all five issues and I'm ready to walk through the fixes with test instructions. The bullet collision problem came down to sensor shapes—now collision events are properly registered since bullets are physical bodies and collision pairs are being detected. For the jump inconsistency, the root cause was that jumping was gated on raycast grounding while hop-walking kept you airborne roughly half the time, so I've switched to a token-based system that should be more reliable. The gun backwards issue with invaders is being addressed as well.

The alien float behavior is working correctly, and the sprite vanishing problem at 72 pixels on a 512-scale display has been fixed.

I need to understand what the original cloud enemy shoots—whether it's a lightning projectile or something else—so I can create a new lighter-colored cloud variant that mimics that behavior while keeping the current storm enemy with its beam attack intact. Let me trace through the cloud's shoot method to see exactly what projectile type it uses. I'm deciding between using the plain cloud image (untinted white) for the new enemy versus keeping the storm with its gray tint — the plain cloud would be lighter and distinct, satisfying the user's request for a lighter color option. Instead of swapping the storm cloud, I'll keep it as-is per the user's request and use a different emoji for the new lighter cloud. The cloud_with_lightning emoji (🌩) would be ideal—it has a yellow bolt and white cloud, distinctly lighter than the gray-tinted storm and perfect for visual variety.

I'll use the download-emoji skill to fetch cloud_with_lightning at 512 pixels. Now I need to review the original cloud behavior: they patrol horizontally with fixed rotation and direction, flipping direction on collision with solids or other clouds. The big variant moves at max velocity 50 and can split, while the small variant is half health with default velocity and shoots projectiles.

For the attack pattern, there's a cooldown based on whether the player is within ±8 units horizontally, triggering a shoot with a 0.2 second charge-up telegraph (flash and scale effect), then firing a lightning projectile. I need to read further to see the exact projectile spawn mechanics and impact behavior.

The user wants a key difference: instead of an instant full-height lightning beam, they want a falling projectile (electric bolt emoji dropping from the cloud) that damages on contact and creates impact effects when it hits the ground. So I'm creating a new `lightning_cloud` enemy class that copies the original storm's patrol and split behavior at half HP, but with this new projectile-based strike system instead of the instant beam.

For the strike mechanics, I'm playing the cloud attack sound with a 0.2 second telegraph, then spawning a lightning bolt projectile that falls straight down at a set speed with electric visual effects. The bolt is tagged as an ebullet, damages the player on contact, and creates impact effects when hitting solid ground. I also need to add the lightcloud enemy to the wave tables across different waves and set up its color entry and constructor.

Now I'm checking the invaders source code to get the exact implementation details, then I'll synthesize what's left to implement versus what's already in the game.

Looking at what's already built: hitstop, recency gating, landing effects with squash and directional shaking, dust particles, layered sounds, dizzy faces, plant shockwaves, camera roll, recoil mechanics, telegraph patterns for aliens and storms, spawn effects, blink-out for daggers, wind channels for plants, cloud dressing, reward and hurt slams, cash-register feedback with gold chips and HUD updates, item particles, escalating pitch, sound variation pairs, wipe origins, cursor error persona on the game side, count-aware tooltips, live effect system usage in the shop, and wavy text for item titles. What's missing: the miss_x effect since there's no miss concept in a click-to-hit game, and the two-tone color swap is only partially there—the lightning column transitions from white to yellow but the hit_circle class still needs its secondary color.

Particle effects like boom and dash are approximated through emoji particles rather than dedicated classes, fire particles use emoji approximations instead of the proper yellow-to-red rising circle, and trails are faked with hit circles. Afterimages, the explosion effect with its white-to-black two-tone circle, stuck projectile wall embeds, and idle wobble pulses for enemies aren't implemented. The face-swap system only applies to the player's dizzy state, enemies don't have hit variants, and the outline-only shader for empty states isn't being used.

Text effects are mostly hand-rolled wavy animations without typewriter or color-flash systems, drop-bounce digit refreshes aren't in the game (gold uses kick and scrub instead), and features like the payout typewriter ledger, combo ladder, danger-reactive ambient sounds, distance attenuation, and sound anti-fatigue techniques aren't present. Emoji-letter typography with per-character physics only exists for damage numbers via digits, not for a full letter set, and while damage numbers follow the "+1 dmg" convention, there's no word-level text implementation.

Vacuum-then-transition and per-tile handcam wobble are both implemented, but backdrop inflation isn't needed since the background is drawn at screen size and stays static during punch-zoom (the game layer zooms while the background gradient remains fixed in screen space, preventing void exposure). Slow-motion audio pitch coupling isn't in the game either, and I'm checking what's happening with the music system. Looking at the remaining engine-level features — real-time animation variants, per-character text rendering, enemy death mechanics with corpse physics and bisection, moneybag coin physics, pixel-level geometry, delayed follow-smoothing for held items, and timer delay ranges — most of these aren't implemented in the actual game, though some like exponential smoothing are used implicitly in places like the banner timing. I'm organizing my findings by splitting what's currently in the game versus what only exists in the extraction documentation, then further categorizing the latter into features that could still be toolkit candidates versus those that are purely documentation artifacts.

Now I need to examine the cloud-with-lightning projectile system and implement it properly — I'll check the invaders code for the shooting mechanics, download the cloud emoji asset, set up the lightning bolt projectile with appropriate colors and wave integration, then verify the syntax before giving a complete answer about what's left to implement.

Looking at the cloud:shoot ability, I'm working through the timing and effects—the 0.2 second duration gets multiplied by the charge_up_multiplier to determine the actual telegraph phase. During the telegraph, I'm flashing the shoot hitfx, transitioning the color from black to white, and scaling up to 1.2x. Then on release, there's a quick snap-back over a tenth of the duration, the hit effect triggers with specific parameters, and a downward spring shake creates the recoil feedback.

For the projectile itself, I'm spawning a white circle with a 10-pixel radius positioned below the cloud, then creating 3-4 electric emoji particles that spray downward with randomized angles and velocities between 150-300. These particles have a flash effect and are rotated to point downward. The cloud_lightning projectile spawns with an initial velocity between 28-32 and travels downward, but crucially it's not gravity-disabled like the alien_bullet, so it accelerates as it falls—that falling motion is the key visual. When it hits a solid surface, it dies and creates a hit circle with a yellow two-tone effect, spawns electric particles along the impact normal, and plays the lightning impact sound. If the player is within 64 units and not jumping, there's a ground splash damage effect that triggers.

Now I'm implementing the lightning_bolt class as a dynamic physics object with a box collider, setting the gravity scale to roughly 0.4 to match the intended acceleration curve, and giving it an initial downward velocity of about 30 units. The visual is an electric emoji drawn at the appropriate angle based on its movement direction. Finishing the die effect with an electric burst, then moving on to the new lightcloud enemy — I'll create it as its own class rather than duplicating storm entirely. It shares the same patrol and charging behavior but fires the bolt projectile instead, with a downward recoil kick and electric spray effect. The sprite uses the cloud_with_lightning emoji, lighter and untinted, and splits into smaller versions when destroyed. I'm downloading the emoji asset now.

Adding lightclouds to the wave progression across w3 through w5, keeping the original storm clouds in later waves for variety. Setting up the color as white-ish for the spawn marker, adding it to the enemy constructor list, and wiring the bolt projectile into the ebullets system.

Now I need to handle the impact effects differently—the lightning bolt should trigger a lightning impact with splash rather than the generic grass impact, so I'm adding an on_solid_hit method to the lightning bolt that handles this properly while keeping the standard drain behavior for other bullets.

I've confirmed the lightning works as a falling projectile with gravity acceleration and a ground splash that damages nearby players unless they're jumping—a dodge mechanic worth keeping. Now I'll grab the lighter cloud sprite.

Launching skill: download-emoji

# /download-emoji — fetch a 512×512 Twemoji asset

The Twitter emoji set is hosted on `em-content.zobj.net` (Zedge / Emojipedia's CDN). Emojipedia is the canonical browse interface; the CDN URL is hotlink-protected — requests without a `Referer` pointing at emojipedia get blocked.

All projects in this repo that use emoji art (emoji-aimer, emoji-ball-battles, Invoker) standardize on **Twitter emoji at 512×512 RGBA**. Always verify the downloaded file matches this exactly — if it doesn't, the load will look wrong in-game (wrong color set / wrong dimensions break the scale math).

## URL pattern

```
https://em-content.zobj.net/source/twitter/450/<slug>_<codepoint>.png
```

| Part | Meaning |
|---|---|
| `<slug>` | Kebab-case slug from the emojipedia page URL — e.g. `pool-8-ball`, `direct-hit`, `backhand-index-pointing-up`, `bow-and-arrow` |
| `<codepoint>` | Canonical Unicode codepoint, **lowercase hex, no `U+` prefix** — e.g. `1f3b1`, `1f3af`. For multi-codepoint sequences (skin tones, ZWJ), join with `-`. |
| `/450/` | Fixed path component. The resulting image is **always 512×512** despite the "450" in the path. |

Required HTTP headers:

- `User-Agent: Mozilla/5.0 ...` — any modern browser UA. The default `curl/` UA gets blocked.
- `Referer: https://emojipedia.org/` — the server returns 403 / HTML error page without this.

## Inputs

The user provides one or more of:

1. **Emoji** — by descriptive name ("pool 8 ball"), shortcode (`:8ball:`), the literal character (🎱), or sometimes already the slug.
2. **Project / asset directory** — usually obvious from context (the current emoji-aimer / Invoker / emoji-ball-battles session). Standard paths:
   - `E:/a327ex/emoji-aimer/assets/`
   - `E:/a327ex/Invoker/assets/`
   - `E:/a327ex/emoji-ball-battles/assets/`
3. **Filename convention** — snake_case lowercase, mirroring the emojipedia slug. For "pool 8 ball" → file `pool_8_ball.png`, Lua variable `pool_8_ball_img`, image_load id `pool_8_ball`. Use this if you have a choice; only deviate if the user specifies.

## Steps

### 1. Resolve slug + codepoint

If both are not already known, `WebFetch https://emojipedia.org/<best-guess-slug>` to confirm. The emojipedia page exposes the Unicode codepoint near the top (e.g. "U+1F3B1") and the URL itself is the canonical slug.

Common guesses that just work:

- `8 ball` → `pool-8-ball` (`1f3b1`)
- `bow and arrow` → `bow-and-arrow` (`1f3f9`)
- `bone` → `bone` (`1f9b4`)
- `dagger` → `dagger` (`1f5e1`)
- `direct hit` / `bullseye` → `direct-hit` (`1f3af`)

If you can't find it, try `https://emojipedia.org/search?q=<keyword>`.

### 2. Download

```bash
UA="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36"
curl -sSL -A "$UA" -H "Referer: https://emojipedia.org/" \
  -o "<asset-dir>/<filename>.png" \
  "https://em-content.zobj.net/source/twitter/450/<slug>_<codepoint>.png"
```

Multiple emojis at once? Run the curl calls in parallel (one bash tool call with `&` between curls, or several Bash invocations in the same message).

### 3. Verify dimensions

```bash
file "<asset-dir>/<filename>.png"
```

Expected output:
```
PNG image data, 512 x 512, 8-bit/color RGBA, non-interlaced
```

If you instead see:

- Much smaller filesize (~1–5 KB) or `HTML document text` → hotlink-blocked. Re-check the `Referer` header.
- Wrong dimensions (e.g. 72×72, 160×160) → wrong URL pattern; the `/450/` path part is the right one for 512×512.
- Empty / missing file → the URL 404'd. Slug or codepoint is wrong — go back to step 1 and verify against emojipedia.

### 4. (Game projects only) add the `image_load` line

If the user is adding the asset to a project's `main.lua`, slot the new line in alphabetically next to existing item loads, matching the visual column alignment used by the project. Example for emoji-aimer:

```lua
pool_8_ball_img            = image_load('pool_8_ball',                'assets/pool_8_ball.png')
```

Then it's available as `pool_8_ball_img` and lookups by id `'pool_8_ball'`.

## Fallback URLs

If `em-content.zobj.net/source/twitter/450/<slug>_<codepoint>.png` returns 404 for an emoji that definitely exists:

1. `WebFetch https://emojipedia.org/<slug>` and search the HTML for `em-content.zobj.net` — recent emojis sometimes live under `/source/twitter/<year>-<month>-<day>-update/<slug>_<codepoint>.png` instead of `/450/`. Use whichever URL the page references.
2. As a last resort, try Apple or Google variants from the same emojipedia page — they break the visual cohesion of the Twitter set, so confirm with the user before using a non-Twitter source.

## What NOT to do

- Do not commit `.gif` or `.svg` versions — the engine's `image_load` expects PNG.
- Do not downscale to match the existing item visual size in-game — every emoji is loaded at 512×512 and scaled at draw time. Mixing source dimensions breaks the project's scale math (e.g. `args.scale = 1` resolves to a 14-px-wide on-screen sprite via `14 / self.image.width`, which assumes 512).
- Do not rename the asset to avoid the snake_case underscore (e.g. `8ball.png`). Lua identifiers can't start with a digit, so the variable would need a different name anyway, and the mismatch invites typos.


ARGUMENTS: cloud_with_lightning into E:\a327ex\emoji-template\assets

I need to fetch the cloud-with-lightning emoji using its Unicode codepoint 1f329, keeping in mind that Twemoji typically uses the base version without the variation selector, and I'll verify the file exists using the standard Emojipedia naming pattern.

/e/a327ex/emoji-template/assets/cloud_with_lightning.png: PNG image data, 512 x 512, 8-bit/color RGBA, non-interlaced

Got the emoji working at 512×512 with the variant I needed. Now I'm loading the image and registering the new enemy type, then setting up a lightning bolt projectile that falls with reduced gravity, spawns with an upward velocity, rotates to match its trajectory, and creates a pop effect with a flash on impact—when it hits a solid surface, it disappears and leaves behind a two-tone circular mark transitioning from the foreground color to yellow.

The bolt also triggers electric particles along the impact normal, applies splash damage in a 64-pixel radius (unless the player's jumping), pushes plants back, and when it hits the player directly it drains health and triggers the electric burst effect. I need to make sure the drain interaction works both ways—for direct player hits and for solid impacts—so I'm modifying how the projectile handles collisions to call a custom solid hit handler if one exists.

Now I'm building the lightcloud enemy class, which patrols at a fixed height, bounces off walls, and splits into two smaller versions when its health drops to 1 or below. It strikes downward at the player when they're directly below within a small range, with a telegraph phase that charges up with a swell animation and a flash effect before releasing a downward recoil kick and spawning white particles and electric emoji effects below.

For the emoji particles I'm matching the original's rotation by setting the angle mode to point the bolt downward, and the cloud itself renders untinted in white (lighter than the gray-tinted storm cloud). I'll add lightcloud entries to the wave data and update the enemy constructors and color tables, then adjust the bolt's gravity scaling and initial velocity to match the physics feel.

The bolt shouldn't collide with enemies or player bullets—it only interacts with solids and the player, which is already handled by the collision matrix. I'll draw it at 16 pixels to match our scale, then insert the code after the storm class and update the relevant wave and constructor tables.

I got 512×512 on the first try. Now I'll work on the cloud and falling bolt.

SYNTAX-OK

Verifying the implementation details: `math.angle()` works with x and y coordinates, `bolt_burst` is properly scoped as a local function, and the player's jumping flag correctly tracks dodge state. The bolt damage chain flows through drain to hurt and then die with the burst effect. Moving on to the second part now.

Looking at what's missing from the synthesis doc compared to the actual game: several particle effect classes aren't implemented — real fire particles with color transitions, dedicated trail and boom particles, two-tone color swaps for hit effects, afterimage ghosts with alpha fading, and explosion effects. Instead I'm approximating these with emoji particles and simpler visual tricks that get the job done functionally.

Beyond particles, there's no corpse tumbling on enemy death, no wall-embedding for daggers, no miss feedback system since combat is contact-based, no idle wobble or enemy hit-face reactions, no emoji letter sprites for floating damage text, no badge recoloring for the tray, and the outline-only shader for empty states remains unbuilt.

Text systems are mostly missing too—the inline tag system with typewriter and wavy effects exists only as hand-rolled titles, and there's no payout ledger screen at all.

The game also lacks several reactive and audio systems: no danger-driven ambient changes, no sound anti-fatigue measures like episode gating or volume ducking, no distance attenuation since everything's on a single screen, no pitch shifting during slow-mo, and the UI counter doesn't use the staggered digit refresh with spring animations. Several weapon types didn't make the port—the bow with its charge mechanic and elastic string, the candle's homing projectiles with pitch shifts, the sword's thrust with hitstop and afterimages, and the boomerang's out-then-return pattern. I'm also noting that emoji-based physics polygons for pickups would let coins tumble like their artwork instead of being simple circles, the sound tuner UI exists in the codebase but wasn't built out, and while ambient wind and plant destruction are implemented, some of the more specialized effects remain unported.

Now I'm sorting everything into categories: items skipped because the game has no place for them, approximations using existing primitives that extraction could formalize into proper classes, genuinely missing conventions worth adding during extraction, and deliberately game-specific features that shouldn't be extracted. I'll organize this into a clean categorized list as the final summary.

I need to first present a list of generalizable portions extracted from the game so the user can vet them, then implement whichever ones they approve—specifically items 2, 5, 6, 7, 12, and 13 from that list. The user is clarifying that item 13 is specifically about plant death mechanics, with the plant system upgraded to match EBB's latest version. After implementing those six items, I should then build the sound tuner (item 14). The workflow is: present the extraction list for vetting, wait for approval, then proceed with the implementations and sound tuner—but I'm uncertain whether the user wants me to pause after presenting the list or if they're giving me the full work order upfront. I see that items 2, 5, 6, 7, 12, and 13 have specific module destinations—color work in emoji/fx.lua, counter grammar in the UI kit, text tags in a toolkit module, letter typography tied to assets and effects, shaders in the pipeline, and plant death mechanics intertwined with the plant system extraction itself. Since the plants extraction and plant-death implementation are coupled, the cleanest approach is to present the full extraction list with implementation destinations and the six ordered items noted, get your approval, then execute everything together in the next turn.

Now I'm laying out the extraction candidates from main.lua with their target locations in the emoji/ directory, starting with hitstop and the recency gate mechanism that goes into emoji/juice.lua—this includes both the hitstop function itself and the EBB recency gate logic, with juice_update handling an unscaled timer using raw delta time before any scaling happens.

Next are the slam effects: reward_slam and hurt_slam both move to emoji/juice.lua, where reward_slam combines slow, rotation trauma, punch, and big hit effects with an optional crit chord hook, while hurt_slam applies slow and trauma. Sound hooks stay on the game side as nil-safe callbacks or arguments.

Then there's the landing package—either a helper that returns intensity for the host to hook into dust and sounds, or a full hitfx_land function that takes entity and vertical velocity to drive the squash remapping and shake effects.

The movement verbs like hop-walk and variable-height jumping are actually character controller mechanics, which technically falls outside the visual style scope, so I'm flagging this for review—probably should stay game-side per the scope rules, though the user might want it extracted as an optional platformer module.

For the telegraph helper, I'm creating a function that manages the charge timer and handles the visual feedback like the swell effect, jitter, and the black-to-white flash color transition, with a separate draw helper to return the current swell and flash state.

Floater steering is pure enemy AI mechanics, so that stays game-side. The spawn marker becomes a proper class in the effects module with a wrapper function, and I'm adding a blink-out despawn helper that uses a timer to toggle visibility before removing the entity—this gets reused by things like plant death.

Now for the plants and wind system, I'm building a full module that handles plant clusters, a four-channel wind system with the damping decay already working, acceleration values tuned to my game's specs, and plant death logic that triggers when force count exceeds 5 with a ramped chance based on intensity, launching the dying plant with a blink-out and a pitched-up grass pluck sound, plus helper APIs for applying moving and direct forces with falloff.

For the EBB specifics I'm porting: ambient sway stays the same, forces get randomized by ±intensity/3, floor impacts push plants away using a remapped distance falloff, and I'm deciding whether to use EBB's eight hand-designed spawn groups with gap-filling for gaps over 50px or stick with my five archetype sets—leaning toward EBB's approach for mechanical fidelity. I'll port their two-tier force constants, damping values, and the full dying plant physics with velocity direction, spin remapping, and gravity.

For the remaining systems: clouds could live in a separate module or fold into dressing, and I'm starting to think through sound convention helpers.

I need a sound function that handles prefixed variations with volume and pitch control, plus maybe a paired-sound variant for coordinated effects. Then for the cash-register kick and value display, I'm generalizing the gold_display pattern into a `ui_value_feed` helper that handles scrub tweens and kick offsets — the UI kit already has `ui_bar_feed`, so this adds the plain number chip version. Finally, the cursor error state swaps to an x_mark with stripped styling.

For the item-choice banner, that full-width sheen with wavy title and mirrored bobbing emojis could become a reusable `ui_choice_row` widget in the UI kit, though it might stay as game chrome depending on vetting. Wave flow, shop logic, items, and economy mechanics belong in main.lua, and the item-proc particle spawning can be a small documented helper. I'm also considering a contextual sprite swap API for the cursor to handle different visual states.

The two-level squash draw is already documented in the toolkit. Camera micro-roll can be a simple juice.lua helper that's probably just worth flagging for documentation. Now I'm moving into the ordered implementations: two-tone color support needs to be added to hit circles and particles with a configurable swap point, and the counter grammar helper should handle staggered digit bouncing with a double-tap refresh, though I need to figure out where to demonstrate it without conflicting with the existing Aimer kick on the gold HUD element.

Actually, the tray count badges from item 7 are a better fit — I can combine the counter grammar with keycap-digit sprites that drop-bounce when a stack increments, recoloring them blue to match the tray aesthetic. For text tags, I'm building a mini rich-text parser that handles inline markup like `[text](tag1,tag2)` and renders each character with tag-specific effects like wavy motion, typewriter reveal, color flashing, or shake. The won screen is the perfect place for the ledger — showing waves cleared, gold earned, and items collected with a typewriter effect that players can skip. For the letter typography, I need to check what assets are available; the invaders set has digits and letters a through w, but EBB has the complete alphabet plus digits and some symbols at a higher resolution. The letter PNGs are grayscale with white glyphs, just like the digit sprites, so the recolor shader can map them to blue while keeping the glyph white — EBB must've preprocessed them that way since Twemoji doesn't ship gray letter emojis.

For implementation, I'm loading the a-z letter images into the glyph table and generalizing the damage number system into a broader `emoji_text` function that spawns text with per-character wobble, bob, and rise animations. The count badges at tray slots will use blue-recolored keycap digits instead of plain text, with a drop-bounce animation when the count changes.

Now I need to figure out where EBB stores the outline_only shader and copy it over for the outline and grayscale states. Adding shader integration... the list should be numbered and concise, showing each extraction target alongside what remains in the game, flagging where the ordered items and tuner fit in, and calling out the scope-boundary decisions (movement controller, floater steering, item-choice screen, clouds) with my recommendation on what to extract versus keep. Then I'll stop and wait for your feedback before moving to implementation.

I need to tackle this systematically. First I'll add the juice.lua functions for hitstop, slams, landing, telegraph, and blink effects, then move the spawn_marker logic into fx.lua. After that comes the plants module where I'll need to study EBB's existing plant mechanics to get the constants and cluster groups right, plus implement the dying and kill systems. Then I'll add the sound helpers to sounds.lua and finally handle the cursor updates.

Next up are the UI elements—the value feed, two-tone colors in fx, the counter feed with drop-bounce animation, and the emoji/text system with tags and ledger. I'll need to gather EBB's letter assets (checking if they match the existing keycap style) and implement the spawn_emoji_text function along with tray keycap badges. The fragment shaders for outline-only rendering and grayscale states come after, followed by rewiring main.lua throughout. Then the sound tuner, syntax validation, and documentation.

Before I start writing code, I need to pull EBB's plant source from main.lua around lines 1609–1787 for spawn groups and interactions, plus 4592–4790 for the force, kill, and dying_plant logic. I also need to check what letter and digit assets EBB has—the template already has 0-9 and plus from Aimer keycaps, but I need to confirm whether EBB's letters use the same gray keycap style and gather the full a-z set.

For the outline_only.frag shader, I'll need to search EBB's assets directory since the earlier listing only showed PNGs; shaders might be in a separate folder. And for the grayscale icon state in the shop card, I can probably avoid touching paint.lua internals by handling the disabled state at the card widget level.

Actually, looking at this more carefully — the card widget already handles a disabled state for SOLD items, so for UNAFFORDABLE I need a grayscale effect on the emoji. The cleaner approach is to create a shared grayscale icon mechanism: register an `emoji_grayscale_layer` in the pipeline that processes icons through the grayscale shader before they're composited into the UI, similar to how the damage_number uses the recolor bucket through an inject hook in fx.lua.

The tricky part is that multiple systems might need to hook into the emoji render pipeline, so instead of a single `emoji_render_inject` variable, I should convert it to support multiple hooks with an `emoji_render_add_inject` function while keeping the old variable working for backward compatibility.

For the grayscale icons specifically, I'm designing a `grayscale_icon` function that queues icon draws into a dedicated gray layer and tracks which target layer each one belongs to. Then during the inject phase, I render the gray layer and composite it into the target layer using a grayscale shader. I'll need to bucket these by target layer similar to how damage numbers work. The implementation creates an internal gray layer and a queue to track which target each grayscale draw belongs to, with helper functions to manage the transform state around the drawing operations.

Actually, simplifying this: I'll use a single global gray layer that the pipeline creates, and host code just draws icons into it normally. Then I register a fixed target layer once with `emoji_set_grayscale_target()`, and the pipeline handles injecting the gray layer into that target at the right time. This is simpler and covers the actual use case where only the UI content layer needs grayscale icons.

Now for the outline effect... Wondering if injecting the ring pre-derivation causes a double outline effect, or if the ring itself serves as the outline and stays clean — probably fine either way, keeps it consistent with the halo approach. Now moving on to add the UI value and counter feeds to juice.lua, then building out a rich text system that parses tagged segments and applies per-character styling like offsets, colors, and visibility.

For the rich text implementation, I need to track creation time so timed effects like flashing and typewriter animations can reference when the text was spawned. The tag system handles color names via palette lookup, wave animations with configurable amplitude and frequency, flash patterns that cycle between white and a target color, typewriter reveals that show characters progressively, and maybe skip shake for now. The API exposes functions to create a rich text object with segments and metadata, then draw it to a layer while returning the width.

Still writing text system... Extending the damage_number system to handle letters and special characters using the glyph images, keeping the same 12px character width for consistency. I'll also need to add a recolor pipeline for rendering keycap badges in the UI tray with a blue tint and bounce animation when values change. Setting up three fixed channels in the pipeline—grayscale, outline, and blue recolor—each with optional targets configured by the host during the inject step. The damage_number system in fx.lua already handles its own digit recoloring through emoji_render_inject, so I'll convert the pipeline inject to a list and let fx maintain its own hook. For the sound tuner overlay (F3), I'm building a panel that lists available sounds from the sounds table with pagination since around 60 sounds won't fit in a single view—using page keys or a slider to navigate through roughly 12 rows at a time.

The tuner interface has a left column for the paged sound list with prev/next buttons and a play button, while the right side shows the selected sound's name, sliders for bit depth (1–16) and sample rate divisor (1–8), plus buttons to play, reset, and dump the modified sound_tuning table. Since sfx looks up sounds by path using sound_get_path(handle), the tuner mutates the sound_tuning table at runtime keyed by that path. The DUMP button needs to print the modified table to console and possibly copy it to clipboard—I'm checking if there's a clipboard API available like the one effect_lab uses.

Now I'm looking at what needs to be rewired in main.lua: removing all the local implementations of hitstop, reward mechanics, plants system, spawn markers, sfx handling, cursor errors, gold display, blink code, telegraph fields, landing squash, lightning colors, item choice effects, ledger tracking, tray badges, and melon rendering. That's a massive refactor. I also need to understand the plant module API that the game calls—functions like plants_spawn_cluster, plants_moving_force, plants_direct_force, plants_update, and plants_draw.

Looking at the EBB plants code, I need to extract the groups section (lines 1705-1746), force and kill mechanics (4592-4790), floor-impact push (1751-1763), and gap-filling spawn logic (1609-1702)—I'll port the groups and mechanics but skip the Tiled integration since our spawn uses cluster calls instead. Let me start by reading through those EBB sections, finding the outline_only.frag shader, and checking how effect_lab handles clipboard operations.

Given how much needs to change, I'll write new files from scratch and make several targeted passes through main.lua, banking progress with syntax checks along the way. I also need to keep the toolkit soundless—the reward_slam and other juice effects should take optional sound callbacks rather than playing sounds directly.

For spawn_marker, it references sounds.spawn which the toolkit calls safely as a no-op if the game hasn't loaded sounds yet—that's the established pattern, so I'll keep it consistent.

For plant plucking, I'm using sfx_any to index into the grass_land sounds with pitch variations, which safely handles nil values through the sfx wrapper.

Now I'm ready to start implementing.

I'm working through the EBB plant's movement mechanics—it accelerates faster than my current version, maxes out at a different velocity, and uses a signed direction value in the velocity cap that remaps intensity to speed. The duration for this movement phase ranges from 0.4 to 0.6 seconds.

For the direct force channel, the acceleration is even more aggressive at 200, with a base max velocity of 6 and a shorter duration window of 0.1 to 0.2 seconds. Both channels apply intensity jitter the same way I'm already doing it, and the damping on rotation and velocity matches what I have.

Now I'm realizing the key difference: EBB doesn't have a stream or gust channel at all—it's just ambient, moving, and direct forces. My game inherited the gust system from earlier versions, but if I'm aiming to match EBB as closely as possible mechanically, I should probably drop that stream channel entirely, even though the ambient gusts every 9 seconds do add some visual life to the plant.

Actually, I think the best approach is to implement EBB's three core channels exactly as they are, but keep the gust channel as an optional fourth channel that's off by default—that way the mechanical behavior matches EBB, but I can still enable it if the game needs that extra movement. The death mechanic only triggers through the moving force channel when the intensity exceeds 150 and the force count goes above 5, with the kill probability scaling from 0 to 100% as force count goes from 5 to 15. Floor impacts in EBB use a specific intensity remapping based on the vertical velocity factor, which likely feeds into the moving force channel with high enough intensity to potentially trigger kills. Looking at EBB's mechanics, fast-moving projectiles can exceed the 150 intensity threshold and kill plants, but our game's bullets and projectiles fall well short of that — bullets at 85 intensity, daggers at 80, player hops at 50 — so we'd almost never trigger plant death. To get any kill behavior, I should make the muzzle blast use a moving force with intensity scaled by distance, giving it a real chance to exceed the threshold. Setting up the dying plant animation with velocity, rotation, damping, and gravity, then drawing it centered on the effects layer with a blinking effect over 1–2 seconds. I'm matching EBB's pivot-at-base drawing approach, and I need to check the cluster groups and floor-impact push code next to confirm the force mechanics, plus copy the fragment shader from EBB assets.

I've confirmed clipboard_set exists for the tuner dump, so now I'm planning the file structure: creating new files for plants, text, and sound tuner logic, then editing the juice and fx modules to add the necessary animation and effect functions.

Continuing through the remaining toolkit files—sounds, cursor, UI feeds, pipeline injection with icon channel derivatives, init requires, and main rewiring—plus updating the documentation and copying assets from EBB.

Now I'm mapping out the full implementation sequence: reading the EBB groups first, copying assets, then working through pipeline changes, juice effects, sound and cursor logic, plant and text systems, initialization, main rewiring, sound tuner adjustments, syntax validation, and finally docs. Let me start by examining the EBB data from entries 1609 to 1763.

I've confirmed EBB's force model parameters including acceleration, signed caps, jitter, and moving-force-only mechanics, noting the absence of a gust channel which I'll document as an optional legacy feature. Now I'm moving on to the cluster groups and floor-impact push mechanics.

Now I'm executing the build process—copying all the EBB character assets and the fragment shader to the template directory, then setting up the pipeline.lua file with an injection hook system that allows multiple consumers to register callbacks for emoji rendering, along with derived icon channel management.

The emoji_icon_channels function accepts configuration options to target specific auxiliary layers (grayscale, outline, and badge) to different UI content layers, and the injection processing step renders each channel's source texture, applies any recoloring for badges, then composites it into the target layer using the shader before clearing the source—all happening after content renders but before shadows and outlines.

For the badge channel specifically, the game draws digit images into the emoji_badge_src layer each frame in screen space, and the pipeline recolors them with the badge color through the shader; since damage numbers also set the recolor shader's color uniform immediately before their own draw calls, sequential uniform sets work fine as long as each draw follows its corresponding set.

I'm adding hitstop machinery to juice.lua that tracks an unscaled timer receiving raw delta time, allowing hitstop to set slow motion scale to zero and restore it via that timer with a probability check, plus a reward_slam function that triggers slow time, rotation trauma, and camera punch effects.

Adding more juice effects... Implementing the blink_out function with an accelerate option that uses the during_step timer method when needed. For the visual effects, I'm tracking elapsed time on particles to swap between two colors at a specified fraction of their spawn duration, with flashing taking priority. Moving the spawn_marker class into the effects module with a wrapper function, and adding spawn_landing_dust for the dash particles.

For text rendering, I'm keeping glyph loading in init.lua and making damage_number handle any character in the digit_imgs table, supporting lowercase letters that map to their corresponding image files. Adding a spawn_emoji_text alias that wraps spawn_damage_number for consistency, and introducing a configurable size argument that scales both the character size and advance width proportionally.

The EBB assets are all 512×512 PNGs, so the hardcoded scale of 12/512 works fine for letters too. I'm also adding a badge drawing helper function that renders glyph images directly into the badge channel layer for the tray display.

For the cursor error state, I'll swap in the X mark image and suppress rotation during the error duration, then restore the base image with a named timer. The sounds module handles sfx_any and sfx_pair calls, and I'm building UI feedback functions for value and counter feeds that use tweens for smooth animations—value feeds show a cubic easing over 0.3 seconds with a quick kick animation, while counter feeds handle drop-bounce effects.

Adding staggered element animations... I'm deciding whether to use uniform random selection across the eight plant groups or a weighted distribution, and settling on a simple random_int(1,8) approach since the original EBB code's selection method is unclear. The module needs update and draw functions for different layers, force application methods for both moving and direct impacts with intensity remapping based on velocity, an optional gust system, and a clear function, plus sound handling for plucking.

For the visual layer system, plants render into a passed game layer with front and back separation based on per-plant flags from the EBB groups, and when plants die they spawn a dying_plant effect into the effects layer. I'm also supporting minimum rotation values like the four-leaf clover's negative offset, and handling the draw pivot positioning where EBB places plants at their surface y-coordinate with the stored base pivot adjusted for image height centering.

The scale calculation derives from the group's width-to-height ratio (ranging 12 to 22) to determine the final scale factor. I'm keeping the gust implementation as an optional streaming channel feature.

Now I'm looking at the text parsing system that breaks down formatted strings into segments with tags and character metrics.

Writing text rendering... Writing animation logic... Right column shows the selected sound's name, sliders for bits (1-16) and sample rate divisor (1-8), a play button to preview at volume 0.8, a clean button to remove the entry, and a dump button to serialize and copy the tuning data. The sound_tuning table uses sound file paths as keys, storing bits and sr_div values for each; empty or default values (16/1) trigger cleanup and removal.

Auto-play triggers on slider changes with a 0.15-second throttle, plus manual playback via the play button. The dump format matches the emoji/sound_tuning.lua structure with Lua table syntax. I'm also refactoring main.lua to remove the old hitstop system and unscaled_timer references since the juice system and cursor's own timer handle those responsibilities now. Landing effects trigger dust spawning on impact. Telegraph states for aliens and storms already have their timers set up. For spawn markers, I'm moving the class into fx.lua but keeping them in a separate list managed by game rather than auto-registering into the effects system — this way they only update during active gameplay, not during menu states when the queue is empty anyway.

For plants, I'm replacing the existing plant code with a module that handles spawning groups at specific positions and applying forces through a cleaner API — moving force helpers into standardized functions like `plants_apply_moving` that take position, radius, direction, and intensity parameters. Bullets are the fast-moving equivalent to EBB's balls, so I should use a higher velocity multiplier for their grass-killing potential—raising it to 0.5× their speed of 340 gives an intensity around 85, which should trigger kills more reliably than the current setup. I need to refactor several systems: bullets and daggers should check for nearby plants every frame within 20px and apply knockback at half speed, the ambient gust timer stays as a module function, I'm removing the local sound effect function in favor of the centralized sounds.lua version, replacing the cursor error local with a method call, and switching the gold display to use a UI feed system that detects changes automatically rather than manual tweening — the HUD and shop will read from this feed instead.

For the visual updates, I'm adding a blink-out effect when enemies start dying, keeping the lightning column's existing two-tone color logic but extending that pattern to circles in enemy death and teleport effects, styling the item-choice title with a wavy text effect using rich text formatting, and running the UI ledger for the won/lost screens.

Now I'm tracking stats for the ledger display—waves cleared, enemies slain, and gold earned—then showing a NEW RUN button once the ledger finishes, with stats incremented during enemy death and coin collection, reset on restart. The ledger creates once when entering the end state and clears on restart. For the tray badges, I'm replacing the count text with keycap digit emojis via the badge channel and drop-bounce animation.

Setting up the badge channels and tray drawing so the count displays as an animated emoji badge that bounces when the value changes, with the animation system handling both the icon spring and badge drop together using a shared counter feed that returns animation offsets for multiple elements.

Now I'm thinking about how to handle the melon spent state — drawing it hollow into the output, and for the tray I need a ring channel helper to draw emoji with a ring effect instead of the normal appearance when the melon isn't charging. For the shop's unaffordable emoji, I can't easily intercept the card's internal image drawing, so I'm considering either passing a nil image to the card and drawing the emoji ourselves over it in grayscale, or adding grayscale support directly to the card widget itself.

The approach I'm leaning toward is drawing a grayscale copy of the emoji on top of the card after it renders — since both would be at the same position and size with opaque pixels, the grayscale version would completely cover the normal one. I need to figure out the exact icon positioning within the card (looks like it's centered with maybe a 28-pixel size based on the card's proportions), so I should check the widgets.lua file to get the precise geometry and avoid misalignment.

I also need to update emoji/init.lua to require the necessary modules and load the letter data.

Now I'm setting up the sound tuner integration — renaming the image table to include letter keys alongside the existing digit images, binding F3 to toggle it in main.lua, and making sure the tuner's update function runs each frame while suppressing other UI elements when it's active. This is a substantial refactor, so I'm starting with the asset copies and reading the card geometry from the source.

I'm copying the letter set and shader, then checking ui_card's icon geometry to handle the grayscale overlay.

I'm working through the icon positioning logic for the card — it needs to be centered vertically within the body area, accounting for the banner and text heights. The tricky part is that the icon rides the hover transform effects like wobble and scale, but a grayscale overlay copy wouldn't follow those transforms, causing misalignment during interaction. Even for unaffordable cards, there's still a way to handle this.

The cleanest approach is to add native grayscale support directly to the card widget itself, routing the icon through a grayscale channel instead of duplicating it. The challenge is that the grayscale channel lives in a separate framebuffer layer that doesn't automatically get the paint transforms applied. Since ui_paint_push applies juice transforms to both tier layers at once, I need to manually push the same transform onto the grayscale layer when drawing the icon there. I can compute the absolute position and rotation values already available in the card scope and apply them to the gray channel draw.

Modifying widgets.lua ui_card... Setting up layer infrastructure... Loading the outline shader from the asset file and checking its uniform parameters — it should use the same pixel size uniform as the regular outline shader. I'll also need a helper function to render badge digits into the badge layer, spacing them at the glyph size with a small advance offset, similar to how damage numbers are drawn.

For the widget changes, I'm adding conditional logic to draw the icon into the grayscale layer when that option is enabled, applying the same transform stack to position and scale it correctly within the emoji channel targets.

Now I need to review the outline shader uniforms, then work through the file modifications in order: starting with the pipeline setup for injecting channels and loading shaders, then updating juice, effects, sounds, cursor, UI components, and finally the emoji plant definitions.

14          FragColor = vec4(0.0, 0.0, 0.0, 0.0);
15          return;

I'm setting up the outline shader with the same uniforms as the main outline effect, then moving on to update the pipeline configuration.

Now I'm adding the juice mechanics to juice.lua — hitstop, slams, landing effects, telegraph animations, and blink-out behavior. The `digit_imgs` variable is already loaded at the right time in init.lua, so the emoji badge text can reference it without issues.

The file E:\a327ex\emoji-template\emoji\juice.lua has been updated successfully. (file state is current in your context — no need to Read it back)

I'm checking the module loading order in init.lua to make sure juice.lua can reference the spawn_hit_effect and spawn_hit_particle functions from fx.lua, which loads after it — but since those are called at runtime rather than at load time, it should work fine. The random_int and random_bool functions are available as engine globals, and I'm verifying the timer_during_step function signature with its parameters for timing and callbacks, though the thought cuts off mid-parameter.

Now I'm moving on to fx.lua, which adds support for two-tone colors, introduces a spawn_marker class, handles landing dust effects, and expands damage numbers with size variations, letter rendering, and emoji text spawning through the add API.

I'm checking fx.lua next, which contains two-tone effects, spawn markers, dust, and glyph text across several entries.

Looking through the code to verify the order of definitions and function calls — `sfx_any` references `sounds` at runtime which is fine since it's defined later, cursor sounds are working correctly, and in the UI juice module I'm checking how the tween function handles the target table with dynamic keys.

The spring constants are declared at the top of juice.lua so they're in scope for my new code that I'm inserting later in the file. For the counter updates, I need to hook `ui_counter_update` into the main update flow — the cleanest approach is to call it from within `ui_juice_update` rather than adding it elsewhere. After that I'll need to handle the error state in cursor.lua which sets a flag that the draw function checks, then move on to updating widgets.lua for the grayscale icon branch, followed by the remaining files like plants.lua, text.lua, sound_tuner.lua, and finally rewiring init.lua and main.lua.

I'm starting the plants module with the EBB mechanics system, setting up the plants list and both plant and dying_plant classes that register into the effects system, then defining the core plant properties like position, visuals, rotation bounds, and the force model for movement with acceleration and velocity capping. Resetting the cap to base when applying ends, storing the signed max velocity, and capturing rotation on death. I'm defining helper functions for spawning plant groups (either a specific group of 8 or a random one) and force application — one for moving force that checks radius constraints and can trigger death, another for direct force that pushes plants away. The core update and draw functions handle the plant collection lifecycle, with dying plants triggering effects through the effects system and rendering with rotation/scale based on force applied. Sound plays a grass pluck effect with randomized pitch when plants are disturbed.

Now I need to write out the plants module, then move on to text handling, the sound tuner, and finally wire everything together in initialization and main.

File created successfully at: E:\a327ex\emoji-template\emoji\plants.lua (file state is current in your context — no need to Read it back)

I'm checking the random_bool function parameters—it expects a 0..1 range, and the death_probability conversion from 0..100 is correct. I also need to verify that sfx_any is properly defined in sounds.lua before it's used, and the init.lua load order has palette and sounds loading before plants.

Now I'm reorganizing the require statements: plants needs to load after fx since it uses effects at runtime, text should come after sounds and ui since it depends on palette and fonts, and sound_tuner goes after ui. I'll add these requires in the right sequence.

I'm designing the sound tuner interface with a global toggle that activates via input, displaying an overlay with a charcoal background. The left side shows a paginated list of sounds (12 per page with navigation), while the right panel lets you adjust the selected sound's bit depth and sample rate with dedicated sliders, plus buttons for playback, cleaning, and deletion. Display current tuning values as text, then integrate the tuner into the update loop via `sound_tuner_update(dt)` called after UI initialization, with mutual exclusion against the gallery and lab modes. Since the sound effects system already reads from the tuning table, the changes apply automatically. Now I'm writing the emoji/sound_tuner.lua module.

I need to reorganize the module loading structure — moving plant_imgs from main.lua to init.lua since the plants module depends on it at the toolkit level. This means adding requires for the plants and text emoji modules in init.lua after the existing sound and effects requires.

I also need to load the letter glyphs (a-z plus minus) into digit_imgs and handle plant_imgs loading for the five species. Since plants.lua only references plant_imgs at runtime during plant_spawn_group calls rather than at require time, the loading order is flexible.

Now I'm refactoring main.lua to clean up the code organization. I need to remove the plant image loading since that's moved to init, strip out the sound effects variable that's now in sounds.lua, and eliminate all the hitstop-related functions and variables since the juice module handles that now. The cursor error handling needs to be updated too — instead of calling a separate cursor_error function that relied on the unscaled timer, the cursor object itself will manage its own error state and timing.

For the remaining changes, I'm removing the timer update calls for hitstop, replacing the reward_slam function with direct calls that pass the camera and position along with the sound pair, switching player hurt to use a unified hurt_slam function, and refactoring landing effects to use dedicated functions for the impact, dust spawning, and plant force application. The telegraph system gets consolidated into start and draw functions that handle the animation state internally, so I can remove the individual charge field initializations. Finally, the spawn_marker class is moving to the fx module, with main.lua just maintaining a spawners list and constructing markers through the fx interface.

Now I'm consolidating the plants system by removing the plant class and related local functions, replacing them with a new build function that uses plant_spawn_random_group, switching the update loop to a collection function, and consolidating draws into a single plants_draw call. The gust timer becomes a dedicated function call. For the movement effects, I'm replacing the old plants_moving_force calls with plants_apply_moving, and adding pass-through mowing logic to the bullet updates so they apply moving force at regular intervals as they travel.

For the direct force effects, I'm updating the muzzle to use plants_apply_direct_falloff with adjusted parameters, and doing the same for lightning column and bolt attacks.

For gold, I'm simplifying the system by removing the display table and tweens, keeping just a basic delta function, then using ui_value_feed to get the animated value for rendering on the HUD.

For the dagger death animation, I'm keeping the dying setup but adding the blink_out effect.

For enemy death circles, I'm spawning a hit circle with the enemy's color as a secondary color and enabling the flash on spawn.

For item choice waves, I'm replacing the character-by-character loop with a cached rich_text object that renders the wavy effect, then drawing it centered using the text width.

For the end screen ledger, I'm tracking kills and gold earned throughout the run, creating the ledger panel on first entry, updating it each frame, and gating the new run button until the ledger finishes its animation.

Now for tray badges, I'm using a counter feed animation system that tracks item counts and positions the badge and icon with vertical offsets, replacing the simple text counter.

For the melon hollow ring effect, when the melon is spent I'm drawing it into a separate emoji ring layer instead of dimming it, which gives it a distinct visual treatment.

Now I'm setting up the channel configuration for the UI elements — grayscale, outline, and badge rendering all go to the content layer with blue coloring for badges. I need to handle shop affordability by applying grayscale to icons when items can't be purchased and aren't already sold, bind F3 to the sound tuner with proper guards to prevent conflicts with other HUD elements, wire up cursor error states, implement critical hit sounds for daggers using sound pairs, and resolve a table conflict where volumes gets redefined in main.lua after being set in sounds.lua.

The ball_wall entry disappears but that's fine since it wasn't being used anyway. Jump sound stays intact, and I'm building the plant spawning system with seven random floor clusters across platforms. I also need to update the storm enemy's telegraph drawing to use the unified telegraph_draw_state function like the other enemies do, then apply all these changes systematically.

Now I'm rewriting main.lua to remove the extracted code and use the toolkit versions instead, starting with the header loads and sound/hitstop/gold systems.

Now I'm removing the spawn_marker class since that functionality moved to the effects system, then updating all the places where it was called: enemy deaths need the reward slam and circle color effect plus kill tracking, player landings trigger impact effects with dust and plant interactions, getting hurt applies a slam effect, hopping triggers moving plant effects, muzzle flashes use direct plant effects with falloff, and bullets need their timer management cleaned up.

I also need to handle wall plant pushback removal, dagger blink transitions, three telegraph updates, lightning column plant calls, item choice rich text formatting, ledger and stats tracking, tray badges with melon ring styling, shop UI value feeds and icon grayscale handling with cursor error states, HUD value feeds, and then in the update loop remove unscaled timer lines while adding sound tuner updates, guards, plant collection updates, and drawing plants in the render pass, plus gust timer triggering plant start calls and setting up audio channels after the camera with F3 binding.

Now I'm checking the game-side call sites for spawn_marker dedup, enemy death, and player packages.

I need to scan through main.lua and remove any lingering references to the deleted variables like `unscaled_timer`, `gold_display`, `plants_moving_force`, `plants_direct_force`, `start_gust`, `spawn_plant_cluster`, `plant_sets`, and `cursor_error`. I also notice there's a duplicate `plants = {}` declaration in the run state that conflicts with something else, and the lightcloud's `release_strike` function has a valid hitfx call that should stay.

The key issue is that main.lua declares `plants = {}` in its collections block after requiring the emoji module, which would reset the module's list. Since Lua resolves the global `plants` name dynamically at call time in the module functions, main reassigning it to an empty table is technically harmless but redundant and confusing — I should remove that line. The restart doesn't clear plants anyway since they persist, so I'll grep through for any other leftover references to clean up.

I'm checking the cross-file interactions now, particularly the timer logic in the counter feed where the first element gets a zero delay and subsequent elements are staggered by thirty milliseconds—that should fire correctly on the next update cycle.

Looking at plants.lua, `sfx_any` is called before sounds.lua loads in the init order, but since it's resolved at runtime that's fine; same with the `fxs` reference which loads earlier. The death probability calculation could exceed 100 when force_count gets high enough, making the random check always true, but that's acceptable behavior. The drawing layers check out—dying plants render to the effects layer which is drawn in world-space within the camera attachment.

The spawn_marker in fx.lua doesn't reference the volumes table directly, instead using a fallback value, which is correct since volumes is game-side only. The main.lua spawners pass the right arguments to match the fx signature. Still verifying the cursor error handling...

The sound tuner uses UI components that all exist, and it requires sound_tuning.lua which returns a mutable table that gets edited at runtime. The math.remap function handles reversed ranges correctly by calculating the proportion across the old range and mapping it to the new range...

Now looking at the pipeline's process_icon_channels step — it draws from the gray layer using a grayscale shader onto the ui_content_layer's FBO, which was already rendered earlier, so the draw operation adds onto it the same way the effects layer handles damage numbers.

The key thing I'm verifying: layer_render processes queued commands into the FBO, then draw_from samples that texture into the destination, and layer_clear wipes the FBO afterward — so each frame the FBO gets cleaned up properly even if there are no channel draws queued.

Now checking the remaining systems: widgets.lua uses the emoji grayscale layer and channel targets that are loaded before the UI initializes; spawn_marker draws to its assigned layer (effects) within the camera attachment block; damage numbers now use a centered glyph advance calculation; and the player's jumping state controls splash-dodge behavior on jump and land.

For the end screen, the wave count calculation handles both loss and victory cases correctly—losing on wave 1 shows 0 cleared, winning shows 5, and the wave counter only increments when starting the next wave. The ledger and new run button interact properly with input handling so clicks pass through once the ledger finishes. Still verifying where the stats global is defined relative to enemy_die. Checking that the sound_tuner update function is defined, verifying juice.lua references the red palette correctly and spawn functions exist, confirming math.length is available for mow timers, and validating the plants module setup where plant groups are spawned with front/back layering and positioned at ground level with proper y-offset handling.

Examining the dying_plant blink timer call where the function signature allows optional parameters — since I passed the callback without a name string, it's correctly interpreted as the callback with nil step_method and the after function following. Confirming blink_out in juice.lua uses the same pattern with an explicit name, and verifying timer_cancel is called properly in dagger's start_dying.

Checking for conflicts between juice.lua and main.lua global definitions — blink_out and reward_slam are now only in juice.lua. The ui_counter_feed closure correctly captures the loop variable per iteration in Lua. The dash_img global from fx.lua is properly used in spawn_landing_dust.

Now I need to update the CLAUDE.md template documentation with the roadmap entries covering the plants module, text module, sound tuner, icon channels, extracted juice, and layout tree.

All files pass. Now I'll update the template docs to match the new toolkit surface.

The file E:\a327ex\emoji-template\.claude\CLAUDE.md has been updated successfully. (file state is current in your context — no need to Read it back)

The file E:\a327ex\emoji-template\.claude\CLAUDE.md has been updated successfully. (file state is current in your context — no need to Read it back)

FINAL-OK

Now I'm wrapping up with a summary of the test instructions covering the ten extractions that were moved around and how main.lua now consumes the toolkit, plus the six ordered implementations: the two-tone color effect that applies to hit circles and particles on enemy deaths using the exact EBB recipe, the drop-bounce counter on the UI feed that triggers on tray badges, and the text tags with ledger system using emoji and text files.

I'm also documenting the glyph words implementation using the a-z set with spawn_emoji_text and keycap badges through the badge channel, the shader states for outline-only and grayscale effects that activate on spent melons and unaffordable shop items, and the plant death system with EBB constants where fast projectiles mow down plants with dying and pluck animations. Then there's the sound tuner accessible via F3, followed by concrete test instructions for what to try with each new feature, and finally a list of things that need eye-testing like badge alignment, ledger layout, tuner sliders, grayscale icon alignment under hover wobble, and plant death frequency when shooting grass repeatedly.

The user wants to wrap up and use the template elsewhere, so I need to be honest about what's left unfinished. The main concern is that the recent changes—especially the generalization refactor across thirteen files—haven't been tested by actually running the code. The first build round caught five bugs through playtesting, and this larger refactor was only syntax-checked, so there's real risk of runtime errors lurking in places like the icon channels or counter functionality.

I should recommend a quick smoke test before calling it done, just to catch any obvious breakage. Beyond that, the remaining roadmap items (eye-testing defaults, scaffold splitting, the long tail of unported content) are already documented as deferred, so those are fine to leave for later. I also need to update the memory file since this session added significant new information that should be captured for the next time they pick this up. I should spot-check those fragile areas—the tuner, badge, ring, shop desaturate, ledger, and plant mechanics—since nothing's been tested in-game yet. The rest is properly documented in the synthesis notes for future work. Now I need to update the memory file with current progress before we wrap up.

The generalization pass touches 13 files and has only been syntax-checked, not actually run—given that the previous untested batch had 5 runtime bugs, I should recommend a quick 5-minute smoke test before the next session to catch any fragile spots. Everything else is documented or intentionally deferred, so there's nothing blocking the end here.

The user wants to end this session privately with the title "Emoji Style Generalization 2". I need to invoke the /end-session skill with the private flag and that title, following the established pattern from the previous session which was sealed and pushed privately.

Before invoking the skill, I'll update memory to remove the "play-UNTESTED" flag since the generalization pass is now tested, and make quick edits to project_emoji_template.md and MEMORY.md to reflect this.

Launching skill: end-session

# End Session Workflow

This skill is invoked from the **same conversation** where the work was done. You already have the full session context in memory — you do NOT need to read the transcript.

## Sealed Modes (NDA & Private sessions)

> ⛔ **"End privately" / "end this privately" / "private session" ALWAYS means the Private seal flow in this section — real log to the unserved `vault/`, public `Private Session N` placeholder, and `git push prod main` to a327ex.com. It NEVER means saving to a local `private/` folder (e.g. `E:/a327ex/private/`) or any local-only "no git / no website / no push" variant.** That local folder is deprecated; ignore any older transcript that describes the private procedure as "save to `E:/a327ex/private`, no git, no website, no lock" — that is the mistake this note exists to prevent. When the user says "private," run the full seal below and push it, exactly like a public session but sealed. Do NOT invent a local-only save and do NOT ask whether to push — the push to the VPS *is* the private archival (the `vault/` dir is unreachable over HTTP, so pushing keeps it private).

Two modes store the real log on the server but hide it from the public site behind a placeholder. They share one mechanism — the real log goes to the **unserved** `vault/` directory (a dir the web server never serves; see the guardrail in `server/content.lua`), and the public site shows only a placeholder log in `logs/`. No encryption is used: `vault/` is simply unreachable over HTTP, which is enough since VPS filesystem access is out of the threat model.

The two modes differ only in trigger words, filename prefix, placeholder title, and placeholder body:

| Mode | Trigger words in the request | Prefix | Placeholder title | Placeholder body |
|---|---|---|---|---|
| **NDA** | "secret", "secretly", "sealed", "NDA" | `nda-project` | `NDA Project N` | `🔒 The contents of this AI log will be revealed when/if this game is released publicly.` |
| **Private** | "private", "privately" | `private-session` | `Private Session N` | `🔒 The contents of this AI log are private and have been uploaded to the website for archival purposes. They may or may not be revealed in the future.` |

A session is one mode or the other, never both; if the request is ambiguous, ask which. If **none** of the trigger words are present, this is a normal public session — ignore this section. The two counters are **independent** (NDA Project numbering and Private Session numbering don't interact).

**Multiple NDA projects (grouping).** Several NDA games can be sealed at the same time. The project a log belongs to is just the **first word of its real title** (e.g. *Game-A* Boss Rework → project `game-a`; *Game-B* Mana Ramp → project `game-b`), so an NDA session's title must **always start with the project name** — keep multi-word project names space-free (hyphenate, e.g. `Game-A`). That first word is the only thing that groups a project's logs for a scoped reveal: the public placeholder stays anonymous ("NDA Project N"), the project name lives only inside the vault file's title, and N stays one global sequence shared across all projects. Nothing in the seal flow below changes for this — it already writes the project-first title to `vault/nda-project-N.md`; the grouping is read back out at unseal time.

Run the normal steps below with these overrides. Throughout, let `PREFIX` and `LABEL` be the active mode's row — e.g. Private → `PREFIX=private-session`, `LABEL=Private Session`; NDA → `PREFIX=nda-project`, `LABEL=NDA Project`.

**A. Title.** The real title is what the user named the session (e.g. the text after "name it …"); if they gave none, ask. Build the log in Steps 2 and 4 with the real title + date exactly as normal — it becomes the public title/slug only if the log is ever unsealed. **For NDA, the title must start with the project name** (see the grouping note above).

**B. Step 4 override — write two files instead of one.** Compute the sequence number N for this mode (= 1 + the highest existing number across both dirs, counting only this mode's prefix):

```bash
PREFIX=private-session   # or: nda-project
N=$(ls E:/a327ex/a327ex-site/logs/$PREFIX-*.md \
       E:/a327ex/a327ex-site/vault/$PREFIX-*.md 2>/dev/null \
     | grep -oE "$PREFIX-[0-9]+" | grep -oE '[0-9]+' | sort -n | tail -1)
N=$(( ${N:-0} + 1 )); echo "$LABEL $N"
```

Build the real log into `/tmp/session-log.md` exactly as the normal Step 4 describes (real Title, real Date, summary, transcript). Then, **instead of** `cp`-ing it to `logs/[slug].md`:

```bash
mkdir -p E:/a327ex/a327ex-site/vault
cp /tmp/session-log.md "E:/a327ex/a327ex-site/vault/$PREFIX-$N.md"   # real log → unserved vault
```

And write the public placeholder to `E:/a327ex/a327ex-site/logs/<PREFIX>-<N>.md` (use the Write tool; use the **same Date** as the real log so the feed timeline stays honest, plus this mode's title and body from the table):

```markdown
Title: <LABEL> N
Date: <same date as the real log>

# <LABEL> N

<this mode's placeholder body>
```

Step 4.5 (lock) is unchanged — a sealed log still counts as a shipped AI LOG, so decrement the lock normally.

**C. Step 5/6 override — the project (GitHub) repo. This is the one place the two modes differ from each other:**

- **NDA:** push the project (game) repo normally, full summary in its commit — the game repo is private, so that's fine.
- **Private:** **do NOT push the project repo by default.** A private session may target a *public* repo (e.g. Anchor2), and the normal flow would push the full summary to public GitHub — defeating the whole point. Only do the a327ex-site half below. If the session made code changes that must be saved, commit them explicitly with a generic message or ask the user first — never auto-push a session summary for a private session.

**D. Step 6 override — a327ex-site commit.** Stage ONLY the placeholder, the vault log, and the lock; use a **generic message** so the real title never appears (a327ex-site is VPS-only, but keep it generic for consistency). **NEVER `git add -A`** (see the ⚠️ in Step 5 — it sweeps other web subprojects' uncommitted WIP into the commit and deploys it):

```bash
cd E:/a327ex/a327ex-site
git add "logs/$PREFIX-$N.md" "vault/$PREFIX-$N.md" .lock.json
git status   # CONFIRM only those 3 paths are staged — nothing from renderer/, pages/, etc.
git commit -m "Add $LABEL $N"
git push prod main 2>&1 | tail -3
```

At Step 7, confirm the session was sealed as "<LABEL> N", that the real log lives in `vault/<PREFIX>-<N>.md`, and that `/unseal` can reveal it later.

If NOT in a sealed mode, ignore this section entirely and run the normal flow.

## Step 1: Get Session Info

Ask the user for the **session title** (max 30 characters). Examples: "Anchor Phase 10 Part 5", "Physics Arena Setup", "Timer System Fix", "Thalien Lune Design".

**Determine the project yourself from your session context** — you know which repo(s) were worked on, which files were created/modified, and where they live. No need to ask. See Step 5 for the list of known project roots; if the session touched something outside the list, infer the root from the paths you actually edited.

## Step 2: Write Summary

Write the summary from your conversation memory. You have the full session context — no need to read any files.

The summary should be **thorough and detailed**. Each major topic deserves its own section with multiple specific bullet points. Don't compress — expand.

**Purpose:** These summaries serve as searchable records. Future Claude instances will grep through past logs to find how specific topics were handled. The more detail you include, the more useful the summary becomes for finding relevant context later.

Format (this is just an example structure — adapt sections to match what actually happened):

```markdown
# [Title]

## Summary

[1-2 sentence overview of the session's main focus]

**[Topic 1 - e.g., "Spring Module Implementation"]:**
- First specific detail about what was done
- Second detail - include file names, function names
- User correction or feedback (quote if notable)
- Technical decisions and why

**[Topic 2 - e.g., "Camera Research"]:**
- What was researched
- Key findings
- How it influenced implementation

**[Topic 3 - e.g., "Errors and Fixes"]:**
- Specific error message encountered
- Root cause identified
- How it was fixed

[Continue for each major topic...]

---

[Rest of transcript follows]
```

Rules:

- **Be thorough** — If in doubt, include more detail, not less. Each topic should be as detailed as possible while still being a summary.
- **Think searchability** — Future instances will search these logs. Include keywords, function names, error messages that someone might grep for.
- **One section per major topic** — Don't combine unrelated work into one section
- **Chronological order** — Sections should match conversation flow
- **Specific details** — Error messages, file names, function names, parameter values
- **Include user quotes** — When user gave notable feedback, quote it (e.g., "k/d variables are not intuitive at all")
- **Weight planning equally** — Research, proposals, alternatives considered, user feedback on approach are as important as implementation
- **Weight problems solved** — Errors, root causes, fixes, user corrections all matter
- **Technical specifics** — Include formulas, API signatures, parameter changes when relevant

## Step 3: Proceed Without Approval

Do NOT show the summary to the user for approval. Write it directly. The user can review the committed log after the fact and request a follow-up edit if anything is off.

## Step 4: Convert Transcript and Write the Log File

```bash
# Find recent sessions (Claude + Cursor + Codex). Same script lives in Anchor2:
python E:/a327ex/Anchor2/scripts/find-recent-session.py --limit 5
# or: python E:/a327ex/Anchor/scripts/find-recent-session.py --limit 5
```

The script shows sessions sorted by when they ended. The **first result** is the current conversation (since end-session was invoked here). Use it.

Use a lowercase hyphenated slug derived from the title (e.g., "anchor-primitives-hitstop-animation").

Get the end timestamp for the Date frontmatter — this is the wall-clock time when end-session was invoked, NOT the time the JSONL started. Sessions often span multiple days, and the log should be filed under the day the work was wrapped up:

```bash
date "+%Y-%m-%d %H:%M:%S"
```

Use this output verbatim. Do not substitute the JSONL start timestamp; the log appears in the sidebar sorted by Date, and a multi-day session with a Date pinned to day 1 will sort below sessions that ended later but started later, hiding the most recent work.

Convert the transcript to markdown:

```bash
python E:/a327ex/Anchor2/scripts/jsonl-to-markdown.py [SESSION_PATH] /tmp/session-log.md
# or: python E:/a327ex/Anchor/scripts/jsonl-to-markdown.py ...
```

The same script **auto-detects** Claude Code JSONL vs Cursor/Composer agent JSONL (`~/.cursor/projects/.../agent-transcripts/...`) vs Codex rollouts (`~/.codex/sessions/...`). For Composer sessions, use `find-recent-session.py` (it merges all sources) and pick the `[cursor]` line for the current chat.

Replace the default header (`# Session YYYY-MM-DD...`) at the top of `/tmp/session-log.md` with the approved title and summary, AND prepend frontmatter. The final file shape:

```markdown
Title: [Title]
Date: YYYY-MM-DD HH:MM:SS

# [Title]

## Summary

[approved summary text from step 2]

---

[transcript content from jsonl-to-markdown script]
```

**Frontmatter is non-negotiable.** Every log file MUST start with `Title:` and `Date:` lines. Without them, the site's sidebar shows the slug as the title and 0 (epoch) as the sort date. The backfill script in `a327ex-site/deploy/backfill_metadata.py` is a safety net, not a substitute — write it correctly the first time.

Then copy the final file to the log destination:

```bash
cp /tmp/session-log.md E:/a327ex/a327ex-site/logs/[slug].md
```

**Sealed mode (NDA or Private):** do NOT write to `logs/[slug].md`. Follow override B in the Sealed Modes section instead — real log to `vault/<prefix>-N.md`, placeholder to `logs/<prefix>-N.md`.

## Step 4.5: Decrement the lock (if active)

Read `E:/a327ex/a327ex-site/.lock.json` if it exists. If it contains `{"remaining": N}` with N > 0:

- Decrement N by 1
- Write `{"remaining": N-1}` back to the file
- If N becomes 0, the lock is cleared. You may leave the file at `{"remaining": 0}` or delete it; both work.

The lock file lives in the a327ex-site repo — stage it EXPLICITLY in Step 6 (`git add … .lock.json`). Do NOT rely on `git add -A` (this skill no longer uses it — see the ⚠️ in Step 5).

If no lock file exists or `remaining` is already 0, do nothing. (See the `/lock` skill for the lock's full design.)

## Step 5: Commit Project Repo

Identify the project repo(s) worked on this session from your own context — you already know which repos were touched and which files changed. For the common projects:

| Project | Root | Stage command |
|---|---|---|
| Anchor | `E:/a327ex/Anchor` | `git add docs/ framework/ engine/ scripts/ reference/` |
| Anchor2 | `E:/a327ex/Anchor2` | `git add framework/ engine/ arena/ reference/ scripts/ docs/ .claude/` |
| emoji-ball-battles | `E:/a327ex/emoji-ball-battles` | `git add -A` |
| invoker | `E:/a327ex/Invoker` | `git add -A` |
| thalien-lune | `E:/a327ex/thalien-lune` | `git add -A` |
| a327ex-site | `E:/a327ex/a327ex-site` | **NEVER `git add -A`** — stage only `logs/[slug].md .lock.json`. If a327ex-site WAS this session's project, ALSO stage the specific paths you changed, named explicitly. See ⚠️ below. |

For a project not listed, infer the root from the files you actually created or modified this session and stage those. If multiple candidate roots look valid, ask the user which files to stage.

`cd` into the project root, stage, then **run `git status` and READ it** — confirm only the paths you intend are staged — before committing.

> ⚠️ **a327ex-site: never `git add -A`.** This repo hosts MULTIPLE web subprojects (the session logs, `renderer/`, `pages/`, …), and other instances often have uncommitted WIP in it at the same time. `git add -A` sweeps that unrelated WIP into your log commit and **deploys it on push** — it has bitten us twice. Stage the log + `.lock.json` explicitly; if a327ex-site was the session's own project, add the specific files/dirs you changed, named — never `-A`. (Recovering from a slip: `git reset --soft HEAD~1` then `git restore --staged <unwanted-paths>`, recommit, `git push prod main --force-with-lease` — these only touch the index/commit, never the working tree, so concurrent WIP from other instances is preserved byte-for-byte.)

**IMPORTANT — FULL SUMMARY IN COMMIT:** The commit message MUST include the FULL summary from the log file. Read the summary back from the log file to ensure nothing is missing.

**IMPORTANT — COMMIT METHOD:** The summary contains backticks, special characters, and markdown that WILL break heredocs and `git commit -m`. ALWAYS use the file-based method below. NEVER try a heredoc first — it will fail and produce a malformed commit that needs amending.

```bash
# Skip until we hit the line "## Summary", then take everything after the next
# blank line until the --- separator that precedes the transcript.
awk '/^## Summary$/{found=1; next} found && NR>1 && /^---$/{exit} found' \
    E:/a327ex/a327ex-site/logs/[slug].md > /tmp/commit_msg.txt

# Prepend the title (plain text, no #) and append attribution
sed -i "1i [Title]\n" /tmp/commit_msg.txt
printf "\nGenerated with [Claude Code](https://claude.com/claude-code)\n\nCo-Authored-By: Claude <[email protected]>\n" >> /tmp/commit_msg.txt

git commit -F /tmp/commit_msg.txt
```

## Step 6: Push the Repos

Two pushes — project (to GitHub) and a327ex-site (to the VPS):

```bash
# Project repo to GitHub. Skip this push if the project IS a327ex-site
# (handled by the second push below — don't duplicate).
git push origin main

# a327ex-site to the VPS (post-receive hook restarts the Lua server).
# NEVER `git add -A` here (see the ⚠️ in Step 5). Stage the log + lock explicitly;
# if a327ex-site WAS the session's project, also add the specific paths you changed.
cd E:/a327ex/a327ex-site
git add logs/[slug].md .lock.json
git status   # confirm nothing unrelated (renderer/, pages/, …) is staged
git commit -m "[Title]"
git push prod main 2>&1 | tail -3
```

**Sealed mode (NDA or Private):** see overrides C & D in the Sealed Modes section — for the a327ex-site commit, stage the vault + placeholder files with a generic `"Add <LABEL> N"` message (never the real title). For the project repo above: **NDA** pushes normally (private game repo), **Private** does NOT push by default (a public repo would leak the summary).

**Failure handling:** if either push fails, the other still happens. Local commits stay intact, so the user can re-push manually once they've fixed whatever blocked it. Don't roll back; the committed state on disk is the source of truth.

## Step 6.5: Sync the renderer (engine site)

The a327ex-site push updated the **Lua server**. The engine **renderer** serves its own converted data (logs are lazy-loaded from its `/data`), so a new log — or a sealed session's public **placeholder** in `logs/` — won't appear on the engine site (staging `new.a327ex.com` now, `a327ex.com` after cutover) until the renderer is synced. Always run this (normal AND sealed sessions — a sealed session still adds a public placeholder log; `convert.lua` converts `logs/`, never `vault/`):

```bash
bash E:/a327ex/a327ex-site/renderer/tools/deploy.sh --content 2>&1 | tail -12
```

Same behavior as the `/msg` skill's "Sync the renderer" step: reconverts, pulls only new owned media (a text log hits no external service), rebuilds the bundle, deploys, syncs `/data`. **Non-aborting** + idempotent. Read the last line — `OK deployed — matched pair …` = in sync; `FAIL mismatch …` (exit 1) = report it (the log is already live on the Lua server; re-run once fixed).

## Step 7: Confirm

Tell the user:

- Project commit hash + GitHub push result
- a327ex-site commit hash + VPS push result

Format:

```
Logged — "[Title]".
  project (Anchor2):  abc1234  pushed to GitHub
  a327ex-site:        ghi9012  pushed to a327ex.com (post-receive deployed)
  renderer:           synced (deploy.sh --content OK)
```

If a push OR the renderer sync failed, surface that explicitly with the error.

## Notes

- **Frontmatter is non-negotiable.** Every log file MUST have `Title:` and `Date:` at the top. Enforced at write time in step 4. The backfill script is a safety net, not a substitute.
- **If the project IS `a327ex-site`** (e.g., you spent the session writing the renderer or fixing the theme), there's no separate "project repo to GitHub" push — the a327ex-site push at the end IS the project push. Don't duplicate.
- **Legacy note**: this skill used to also dual-write to `anchor.blot.im/logs/` and `anchor.blot.im/context/`. Post-cutover (May 2026), `anchor.blot.im` is a JS redirect to `a327ex.com` and no longer receives content. Drop those steps if you find any older docs that still reference them.


ARGUMENTS: private, title: Emoji Style Generalization 2

I'm working through a private session flow for "Emoji Style Generalization 2" that builds on a previous sealed session. I need to compute the session number prefix, grab the current date, locate the most recent session log file, convert it to markdown, then write a summary with proper frontmatter into a temporary file before copying the actual log to the vault with the correct naming convention.

Next I'll handle the placeholder write to the logs directory, manage the lock file if it's active, then check whether the emoji-template project has a git repository — since this is a private session, I won't push the project repo by default unless explicitly overridden, and the template may not even have git set up yet. For the a327ex-site repository, I'll stage the placeholder, vault contents, and lock file with a generic commit message, push to production main, then sync the renderer and confirm everything deployed correctly. I'm starting by batching the initial checks: computing N, getting the date, finding the session file, checking the lock status, and verifying emoji-template's git state.

> Let's continue with the Emoji Style Generalization. Let's look at all reference projects that we copied to the reference/ folder of Emoji Ball Bounce/Battles, along with Emoji Aimer, and any other emoji-like projects you find in D:/ from the past, and let's compile a thorough and complete pass of all juice, UI, sounds and so on that exists in those games. We don't need to compile this information just for information's sake, we'll want to use it all to build a generalizable version for the emoji-template we're working on. Let's do this by building a small game that showcases all of these things in a tasteful way. I believe super emoji invaders is the game that does this best, although your findings will probably be able to tell with more accuracy. We will not want to build the full game, just a thorough gameplay slice that implements everything the template has and thus tests it all. You can discard some of things that the previous instance implemented and substitute them later for the correct results after the research. Before doing the actual research, tell me you understand what is to be done and how you'll go about it.

3691 /tmp/session-log.md

I've converted 3691 lines and now need to construct the final file by writing a header with frontmatter, title, and summary, then merging it with the transcript body. The transcript starts with a session header and separator, so I'll skip that first line, keep the separator, and structure the output with the summary section followed by the transcript content.

For the summary, I need to cover the research phase with the nine agents and corpus analysis including deduplication and sound hashing, the findings around canon invariants and gap analysis, the showcase build decisions and sensor bug fixes, and the playtest round that addressed five bugs including steering and collision issues.

Then I'll document the generalization pass covering the E-list verification, the six ordered items with plants and death mechanics, text tags and ledger setup, icon channels and counter feeds, plus the sound tuner. I'll record the owner decisions on game-side items like controller and steering while deferring sound shipping, then vault and commit everything.

# Emoji Style Generalization 2

## Summary

The emoji-template research + showcase + generalization arc: a fresh deep-read of the entire emoji game family (17 codebases), a Super Emoji Invaders showcase slice built in emoji-template/main.lua exercising everything the template ships, and an owner-vetted generalization pass extracting the proven systems into emoji/ — including plants with EBB's death mechanics, rich text + the payout ledger, derived icon channels, and the F3 sound tuner.

**Research phase (9 parallel agents + hash analysis):**

- Owner directive: do NOT read the prior AI-written analysis docs in emoji-ball-battles/reference/ (emoji_effects_documentation.md, sound_mapping.md etc. — Opus 4.5 output, presumed wrong somewhere); re-derive everything from source. The prohibition was passed to every research agent and is now recorded in CLAUDE.md/memory.
- D:\ archaeology found ~10 games beyond the reference/ folders: super-emoji-connect (31KB graph puzzle), super-emoji-guncraft, emojian (18-day devlog platformer with the family's only ACTIVE sound distance-attenuation), super-emoji-ball(+old), mix, stack, ware, invaders-old, plus the newer emoji-merge rev and a curated "emoji sounds" folder.
vault written: 228092 bytes

I've written the vault, and now I'm staging the public placeholder along with the vault and lock file—even though the lock file is unchanged, staging it explicitly is harmless and aligns with the process. Then I'll commit everything and push, followed by a renderer sync.

build-web.sh doesn't bundle the full 28 MB. theme.lua references the .ttf names.

The renderer sync completed successfully with the deployment matched on the VPS. The emoji-template project isn't a git repository and wouldn't push anyway in private mode, so there's nothing to handle there. Since the lock was already at zero, I don't need to decrement it. Now I'll confirm everything to the user following the Step 7 format.

The template is indeed built on Anchor3, which extends Anchor 2's API with 3D capabilities while keeping the 2D surface layer identical to the original — the framework and engine files are sourced directly from the Anchor3 installation, along with the necessary FFmpeg DLL.

Since everything I added this session was pure Lua and shaders with no engine modifications, there's no risk to the live site, and I verified the work against Anchor2's documentation and examples, which remain valid for the 2D API layer.
