Brick breaker · glm-5.2

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.

Let me check the working directory and the phaser file.
bash {"command":"ls -la && [ -f phaser.min.js ] && head -c 200 phaser.min.js"}

Let me build the game. I'll create a self-contained index.html with Phaser.

Let me verify it loads without syntax errors by checking the file. I can't run a browser, but I can do a basic node syntax check on the JS portion. Let me just verify the structure is sound. Let me do a quick sanity check that the JS is valid by extracting and running node --check.

Actually, let me just verify there are no obvious issues. One concern: `setMessage` uses `this.add` but is called with `.call(scene, ...)`. In `hitBrick`, `winLevel(this)` — `this` in `update`/collision callback. The collider callback is bound with `this` being the scene (passed as context arg). Good. `hitBrick` calls `winLevel(this)` — `this` is scene. Good.

In `hitPaddle`, `emitSpark(...)` is called without scene context but emitSpark uses `this.time.delayedCall` — `this` would be scene since collider context. Good. But emitSpark uses `particles.createEmitter` — particles is module-scoped, fine.

One issue: `emitSpark` uses `this.time` — `this` is the scene (collider callback context). Good. But in `hitBrick`, `emitSpark` is called — `this` is scene. Good.

`addScore` uses `this.tweens` — `this` is scene. Good, called from hitBrick where `this` is scene.

The winLevel calls `setMessage.call(scene, ...)` where scene is `this`. Good.

Looks fine. Let me just confirm the file is present.
bash {"command":"ls -la index.html && node -e \"const fs=require('fs');const h=fs.readFileSync('index.html','utf8');const m=h.match(/<script>([\\

Done. `index.html` is a fully self-contained brick-breaker game. **What's included:** - **Procedural graphics only** — `makeTextures()` uses the Phaser Graphics API to generate the paddle (gradient bar with highlight cap), the ball (shaded sphere), 6 brick styles (per-row colors with bevels), a particle spark, and a heart icon — no external assets. - **Paddle** — arrow keys (held) or mouse move. Keyboard takes over when pressed; mouse retakes on movement. - **Ball** — bounces off walls and paddle. Paddle hit angle depends on where it strikes (steerable). Sticks to the paddle until launch. - **Brick wall** — 11×6 grid, 6 colored rows with descending point values (60→10). Ball speeds up slightly with each brick destroyed. - **Score & lives** — score HUD with pop animation, 3 lives shown as hearts, ball reset on miss, game over at 0 lives. - **Levels** — clearing the wall advances level, raises ball speed, rebuilds the wall. - **Controls** — Click/Space launch & advance, **P** pause, **R** restart. - Particles (additive-blended tinted sparks) on every paddle/brick hit. Subtle grid + glowing border background drawn via Graphics. Open `index.html` in a browser (with `phaser.min.js` alongside it) to play.
