Brick breaker · gemini-2.5-flash

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.

**Generating Game Code**

I'm currently focused on constructing the `index.html` file. My primary task is to embed all necessary Phaser game code and procedural graphics generation directly within this single file, ensuring no external dependencies are required.

**Crafting Inline Code**

I am now focusing on integrating all game logic and procedural graphics generation directly within the `index.html`. This involves building the Phaser configuration, implementing scenes, and then creating the paddle, ball, and bricks with physics and collision handling, all without external assets.

**Embedding Game Logic**

I am now integrating all Phaser game code and procedural graphics generation directly into `index.html`. This includes setting up the game configuration, creating scenes, and building the paddle, ball, and bricks with their respective physics and collision behaviors.

**Developing Brick Breaker**

I've successfully drafted the `index.html`, incorporating all core brick-breaker game mechanics. This includes the foundational HTML, inline styling, local Phaser integration, and a single scene with essential `preload` and `create` functions.

**Implementing Game Logic**

I've now integrated the complete brick-breaker game logic into the `index.html`. This includes all the necessary HTML structure, inline CSS, local Phaser integration, and a single scene managing preload, create, and update functions, ensuring all assets and graphics are procedurally generated.

I have successfully created the `index.html` file which contains the complete brick-breaker game. It meets all the requirements: it's a single-page app, includes all CSS and JavaScript inline, uses the provided `phaser.min.js` locally, and generates all graphics procedurally. You can open `index.html` in a web browser to play the game.

EVALUATION

4/5 working

Functional brick-breaker with paddle, bouncing ball, score/lives; bricks break and paddle moves via arrows/click.
