Using the pre-provided phaser.min.js (global Phaser), build a playable brick-breaker game with a paddle (arrow keys or mouse), a bouncing ball, and a wall of breakable bricks with a score. Use ONLY procedurally generated graphics via the Phaser Graphics API or generated textures — no external image or audio assets whatsoever.

The user wants me to build a brick-breaker game using Phaser.js with only procedurally generated graphics. I need to create a single index.html file that includes everything - HTML, CSS, and JavaScript. The phaser.min.js is already in the current directory, so I'll load it with a script tag.

Let me create a complete brick-breaker game with:
1. Paddle controlled by arrow keys or mouse
2. Bouncing ball
3. Wall of breakable bricks
4. Score tracking
5. All graphics generated via Phaser Graphics API or generated textures
6. No external assets

I'll write the entire game in one index.html file.
bash {"command":"ls -la phaser.min.js"}

Good, phaser.min.js is present. Now I'll create the index.html file with the complete brick-breaker game.

The file is created successfully. The game is a complete brick-breaker with:
- Procedurally generated graphics using Phaser Graphics API
- Paddle controlled by arrow keys or mouse
- Bouncing ball with physics
- Breakable bricks in multiple colors/rows
- Score, lives, level tracking
- Particle effects
- Procedural audio via Web Audio API
- Start screen, game over screen, pause functionality
- All in a single self-contained index.html file

Let me verify the file is complete and well-formed by checking its content.

The file is complete and well-formed. It contains:
1. HTML structure with game container, UI overlay, start screen, game over screen
2. CSS styling for the game
3. Phaser game configuration
4. Procedural texture generation using Phaser Graphics API (paddle, ball, bricks, particles, grid background)
5. Complete game logic including:
   - Paddle movement (keyboard arrows + mouse)
   - Ball physics with angle-based paddle bounce
   - Brick collision with scoring
   - Multiple levels with increasing difficulty
   - Lives system
   - Particle effects for paddle hits, brick breaks, death, level completion
   - Screen shake and flash effects
   - Pause functionality (P or Esc)
   - Procedural audio via Web Audio API
   - Start/restart screens

All graphics are generated procedurally - no external assets. The game is fully self-contained in index.html.

The brick-breaker game is complete at `/workspace/index.html`. It includes: **Gameplay Features:** - Paddle controlled by ←/→ arrow keys or mouse - Ball launches with Space/Click, bounces with angle-based physics off paddle - 6 rows × 10 columns of breakable bricks with 6 color tiers - Score, lives (3), and level progression - Increasing ball speed per level - Pause with P or Esc **Procedural Graphics (Phaser Graphics API):** - Paddle with rounded corners, highlight, and glow border - Ball with glow aura and specular highlight - Bricks per row color with top highlight, bottom shadow, and colored borders - Particle system for impacts, brick breaks, death, level completion - Subtle animated background grid **Procedural Audio (Web Audio API):** - Paddle hit: dual-tone square wave - Brick break: random melodic triangle wave notes - Launch: rising sawtooth sweep **UI:** - Start screen with controls legend - Game over screen with final score - Live HUD (score, lives, level) - Screen shake/flash on impacts
