Built with [ClaudeKit](https://github.com/carlrannaberg/claudekit).
## Tech Stack
| Category | Tool | Version | Purpose |
|----------|------|---------|---------|
| **Runtime** | [Matter.js](https://brm.io/matter-js/) | ^0.20.0 | 2D rigid-body physics engine |
| **Rendering** | Canvas2D | (built-in) | Fruit drawing, UI overlay, game-over screen |
| **Build** | [Vite](https://vitejs.dev/) | ^8.0.4 | Dev server, ES module bundling, production builds |
| **Testing** | [Vitest](https://vitest.dev/) | ^4.1.4 | Unit and integration tests |
| **Language** | JavaScript (ES Modules) | — | Vanilla JS, no framework |
| **Dev Tooling** | [ClaudeKit](https://github.com/carlrannaberg/claudekit) | — | Git hooks for linting, type-checking, testing, self-review |
## Project Structure
```
src/
main.js Entry point: initializes game, attaches event listeners
game.js Game class: orchestrates engine, renderer, input, state
physics.js Matter.js engine setup, world configuration, walls
renderer.js Canvas2D rendering: fruits, walls, UI overlay
input.js Mouse/touch input handling, drop control
fruits.js Fruit definitions (sizes, colors, labels, progression)
merger.js Collision detection callback, merge logic, scoring
constants.js Game dimensions, physics tuning, timing constants
style.css Page styling
*.test.js Vitest test files
index.html Single HTML page with canvas element
specs/ Feature and bugfix specifications
```
## Getting Started
## Quick Start
```bash
npm install
npm run dev
```
Open the URL shown in the terminal (default: http://localhost:5173).
## Documentation
## How to Play
1. Move your mouse (or touch on mobile) to position the fruit
2. Click/tap to drop it into the container
3. When two identical fruits touch, they merge into the next larger fruit
4. The fruit chain goes: Cherry → Strawberry → Grapes → Dekopon → Persimmon → Apple → Pear → Peach → Pineapple → Melon → Watermelon
5. Game ends when fruits stack above the danger line
## Scripts
| Command | Description |
|---------|-------------|
| `npm run dev` | Start Vite dev server with HMR |
| `npm run build` | Production build to `dist/` |
| `npm run preview` | Preview the production build |
| `npm test` | Run all tests once |
| `npm run test:watch` | Run tests in watch mode |

## Fruit Chain
Cherry → Strawberry → Grapes → Dekopon → Persimmon → Apple → Pear → Peach → Pineapple → Melon → Watermelon
| Tier | Fruit | Radius | Color | Merge Points |
|------|-------|--------|-------|-------------|
| 0 | Cherry | 12px | Red | 1 |
| 1 | Strawberry | 16px | Light Red | 3 |
| 2 | Grapes | 20px | Purple | 6 |
| 3 | Dekopon | 26px | Orange | 10 |
| 4 | Persimmon | 32px | Dark Orange | 15 |
| 5 | Apple | 36px | Red | 21 |
| 6 | Pear | 42px | Green-Yellow | 28 |
| 7 | Peach | 48px | Peach | 36 |
| 8 | Pineapple | 57px | Yellow | 45 |
| 9 | Melon | 64px | Green | 55 |
| 10 | Watermelon | 77px | Dark Green | 66 |
Only the 5 smallest fruits (Cherry through Persimmon) appear as drop candidates. When two Watermelons merge, they disappear and award 66 bonus points.
