Let me analyze what the user is asking for: 1. Build a single-page web app (index.html) with inline CSS/JS 2. Use the pre-provided phaser.min.js (global Phaser) 3. Create a brick-breaker game with: - Paddle (controlled by arrow keys or mouse) - Bouncing ball - Wall of breakable bricks with score - Use only procedurally generated graphics via Phaser Graphics API or generated textures - No external image or audio assets Let me start by checking what's available in the current directory, then I'll create the index.html file with all the code needed. First, I should check if phaser.min.js is present in the directory.

The user wants me to create a brick-breaker game using the pre-provided phaser.min.js, all in a single HTML file called index.html. I need to create a complete self-contained HTML file with: 1. Phaser game using the provided phaser.min.js 2. A paddle (controlled by arrow keys or mouse) 3. A bouncing ball 4. A wall of breakable bricks with procedural graphics 5. A score system 6. Use only Phaser Graphics API or generated textures, no external assets 7. All CSS, JS, and game code inline in the HTML file Let me start by creating the complete HTML file with all the game logic.

Let me check the file I created and open it to make sure it's working correctly. I realize I made an error trying to create textures in the global scope that doesn't work. Let me open the file and fix it.

The user wants me to build a brick-breaker game using the pre-provided phaser.min.js. The key constraints are: 1. Use ONLY procedurally generated graphics via Phaser Graphics API or generated textures 2. No external image or audio assets whatsoever 3. Paddle (arrow keys or mouse) 4. Bouncing ball 5. Wall of breakable bricks with a score 6. Single self-contained HTML file Looking at the current index.html file, it seems like it was created but there might be some issues: 1. The procedural texture creation at the bottom runs in the global scope, not in the proper scene context 2. The createProceduralBrick function creates textures but might have issues 3. The ball texture generation might not work correctly I need to fix the code to make it functional. Let me create a corrected version that properly creates procedural textures within the scene's preload/create lifecycle.

EVALUATION
Game canvas stays entirely black across all frames due to a JS error crashing setup; no paddle, ball, or bricks visible.

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.
- Cannot read properties of undefined (reading '0')
- paddle.setCollisionWorldBounds is not a function
