## What it does

The skill reads your entire project — from `package.json` and `Constants.js` to scenes, entities, UI, and tests — and scores each area from one to five: gameplay feel, visual polish, game over screen, audio, code architecture, restart safety, performance, player experience, mobile support, Play.fun safe zone, gameplay invariants, entity sizing, and test coverage. After the audit it builds a plan of five to eight improvements ranked by impact and waits for you to choose which ones to implement.

Each change follows a strict pattern: constants go into `Constants.js` first, then events into `EventBus.js`, then state fields into `GameState.js`, new files into proper directories, wiring through the orchestrator in `Game.js`. After each fix it runs `npm run build` to catch errors immediately. When everything is done, it runs tests and reports the new score and the list of changed files. It works iteratively — each pass finds the next batch of high-impact fixes. You can focus the audit by passing an argument: `gameplay`, `visuals`, `performance`, or `polish`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill improve-game -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/improve-game/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/improve-game/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill improve-game -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/improve-game/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill improve-game -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/improve-game/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PlayableIntelligence/game-creator improve-game
```

2. **Manually: put the files in place**
- File: `.github/skills/improve-game/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill improve-game -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PlayableIntelligence/game-creator --path skills/improve-game
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/improve-game/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill improve-game -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PlayableIntelligence/game-creator/tree/HEAD/skills/improve-game/SKILL.md

## When to use it
- tune gameplay feel and difficulty progression
- add missing visual polish — backgrounds, particles, animations
- fix restart cleanup — remove listener and timer leaks
- optimize performance — cap delta time, add object pools
- check mobile support — touch input, hit targets, gyro

## Example prompts
- improve my game
- what's wrong with my game
- polish the visuals

# Improve Game

Make your game better. This command deep-audits gameplay, visuals, code quality, performance, and player experience, then implements the highest-impact improvements. Run it as many times as you want — each pass finds the next most impactful thing to fix.

## Instructions

Improve the game in the current directory. If `$ARGUMENTS` specifies a focus area (e.g., "gameplay", "visuals", "performance", "polish", "game-over"), weight that area higher but still audit everything.

### Step 1: Deep audit

Read the entire game codebase to build a complete picture:

- `package.json` — engine, dependencies, scripts
- `src/core/Constants.js` — all configuration values
- `src/core/EventBus.js` — all events and their usage
- `src/core/GameState.js` — state shape and reset logic
- `src/core/Game.js` (or `GameConfig.js`) — orchestrator and game loop
- Every file in `src/scenes/` or `src/systems/` — gameplay logic
- Every file in `src/entities/` — game objects
- Every file in `src/ui/` — game over, overlays
- Every file in `src/audio/` — music and sound effects
- `index.html` — markup, overlays, styles, viewport meta
- `src/systems/InputSystem.js` — input handling, mobile support (gyro, joystick, touch)
- `tests/` — test coverage and quality

Don't skim. Read every file completely so you understand the full picture before making recommendations.

### Step 2: Score and diagnose

Rate each area on a 1–5 scale (1 = broken/missing, 3 = functional but basic, 5 = polished and complete). Present a diagnostic table:

| Area | Score | Diagnosis |
|------|-------|-----------|
| **Gameplay feel** | | Is the core loop fun? Are controls responsive? Does difficulty ramp? |
| **Visual polish** | | Backgrounds, colors, particles, animations, screen effects |
| **Game Over & UI** | | Game over screen, transitions, restart flow, buttons |
```
