Brick breaker · gemini-3.1-flash-lite-preview

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.

**Defining the Core Elements**

I'm now focusing on defining the game's core elements within `index.html`. Using `phaser.min.js`, I plan to create a keyboard/mouse-controlled paddle, a ball, breakable bricks, and a scoring system. I'm keen to leverage the Phaser Graphics API for all visual elements.


**Outlining Initial Implementation**

I'm now outlining the initial implementation steps, considering the single-file constraint. I'm structuring the game with a `Phaser.Game` object and using `preload`, `create`, and `update` scenes. I'll use Arcade physics and Phaser's Graphics API to draw the paddle, ball, and bricks, while setting up the configuration and physics groups within `create`. Score text will also be included. My plan is to use textures programmatically.

The brick-breaker game has been created in `index.html`. It uses the `phaser.min.js` library and procedurally generates its textures for the paddle, ball, and bricks using the Phaser Graphics API. You can control the paddle with your mouse. To view the game, you can open `index.html` in a web browser.

EVALUATION

3/5 working

Functional brick-breaker with paddle, bouncing ball, breakable bricks, and score; paddle doesn't visibly move with arrow/wasd input.

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.
