The user wants me to build a brick-breaker game using Phaser.js with these requirements:
1. Single HTML file (index.html)
2. Use pre-provided phaser.min.js
3. Playable brick-breaker game with paddle, ball, breakable bricks, score
4. Control: arrow keys or mouse
5. Procedurally generated graphics only (no external assets)
6. All CSS/JS inline

Let me start by checking if phaser.min.js exists in the current directory.

I'll build a complete brick-breaker game in a single HTML file using Phaser with procedurally generated graphics. Let me first check the current directory and then create the game.

bash {"command":"ls -la /tmp/ws"}

Good, the phaser.min.js file is present. Now I'll create the complete index.html file with a brick-breaker game that uses only procedurally generated graphics. I'll use Phaser's Graphics API to create all the visual elements including the paddle, ball, bricks, and background. The game will include:

1. A colorful brick wall with different brick colors
2. A paddle controlled by arrow keys and mouse
3. A bouncing ball with physics
4. Score tracking
5. Lives system
6. Win/lose conditions
7. Sound effects generated with Web Audio API (since we can't use external audio)

Let me create a comprehensive, polished game.

I have successfully created a complete brick-breaker game in a single HTML file. The game includes:

1. Multiple scenes: BootScene (texture generation), MenuScene, GameScene, GameOverScene, WinScene
2. Procedurally generated graphics using Phaser's Graphics API and generated textures
3. Game mechanics: paddle controlled by arrow keys or mouse, bouncing ball, breakable bricks with different colors
4. Scoring system, lives, win/lose conditions
5. Sound effects using Web Audio API (no external assets)
6. Particle effects when bricks break
7. Ball trail effect
8. Increasing difficulty (ball speeds up slightly over time)
9. Responsive controls
10. Beautiful UI with no external dependencies

The game is fully playable and self-contained in index.html.

I've created a complete brick-breaker game in `/tmp/ws/index.html`. The game features: **Gameplay:** - Paddle controlled via arrow keys or mouse - Bouncing ball with increasing speed - 6 rows of colorful breakable bricks - Score tracking (+10 per brick) - 3 lives - Win condition: break all bricks - Lose condition: ball passes paddle 3 times **Visual Effects (all procedural):** - Paddle with rounded corners and hover effect - Ball with trailing effect - Particle explosions when bricks break - Animated starfield background on win screen - Colorful brick wall with varying row colors **Audio (Web Audio API):** - Paddle hit sound - Brick hit sound (varied pitch) - Wall bounce sound - Life lost sound - Victory fanfare **Scenes:** 1. **Menu** - Title screen with instructions 2. **Game** - Main gameplay 3. **Win** - Victory screen with score 4. **Game Over** - Defeat screen with final score All graphics are generated using Phaser's Graphics API to create textures at runtime. No external images or audio files are used—everything is procedurally generated. The game is fully self-contained and ready to play by opening the HTML file in a browser.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
