Key constraints: ONLY procedurally generated graphics via Phaser Graphics API or generated textures. No external images or audio. Game: Brick-breaker with paddle (arrow keys or mouse), bouncing ball, wall of breakable bricks, score. - Paddle: Arrow keys left/right or mouse position. - Ball: Bounces on paddle, walls, bricks. - Bricks: Grid of breakable ones, disappear on hit, add to score. - Score: Displayed. - Simple: One level, restart on lose or win. Structure index.html with inline <style>, <script src="phaser.min.js"></script>, <script> game code. Use Phaser 3 config.

The Phaser library is present as phaser.min.js. I need to create a single self-contained index.html that:
The task is to build a playable brick-breaker game using only Phaser.min.js, with all graphics procedurally generated via Phaser Graphics API or generated textures. No external images or audio. It has to be a single self-contained index.html with script tags for phaser.min.js and the game code in a script tag, CSS in style.
I need to write the code for that index.html.
Key requirements:
- Use Phaser v3 (assuming phaser.min.js is v3)
- Procedurally generated graphics only
- Paddle controllable by arrow keys or mouse
- Bouncing ball
- Wall of breakable bricks
- Score
- 800x600 game size probably
- Arcade physics
- Generate paddle, ball, bricks as textures from Graphics
- Bricks in a grid, different colors maybe
- Score display with text
- Simple game over or win
I'll go with 3 lives, lose life on miss, game over when 0 3.
Start with click to launch ball.
Paddle at bottom, mouse to position x, arrows to move.
But to simplify, use mouse to set paddle x, and keys for direction if needed, but since no velocity for paddle, just position.
Paddle is usually moved with velocity, but for simplicity, set position based on input.
Let's plan the code.
First, the HTML structure:
<!DOCTYPE html>

var game = new Phaser.Game(config);
function preload() {
// generate textures
generate textures();
}
function generateTextures() {
var g = this.add.graphics(); // wait, this is not in scope, need to use scene.add
Actually, since in preload, this is the scene.
Yes, preload has this.
// paddle
var g = this.add.graphics();
g fillStyle(0x3498db);
g.fillRect(0,0,120,18);

g.generateTexture('paddle',120,18);
g destroy();
// ball
g = this.add.graphics();
g.fillStyle(0xf1c40f);
g.fillCircle(10,10,10);
g.fillStyle(0xffffff,0.3);
g.fillCircle(7,7,3);
g.generateTexture(' ball',20,20);

The self-contained single-file brick-breaker game is ready at `index.html`. It uses only Phaser.Graphics + generateTexture calls for all visuals (paddle, ball, colored bricks) with no external assets or network requests. Arrow keys + mouse control the paddle, SPACE or click launches the ball. Score and lives are tracked. The game resets cleanly on win or loss.

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.
