Build a Phaser 3 brick breaker game in index.html. Use Graphics-generated textures for the paddle, ball, and blocks. Physics is Arcade. Score, lives, controls (arrow keys + mouse), win/lose states. Let me check if phaser.min.js exists, then write index.html.

Phaser 3. Write index.html containing a complete game. Procedural textures via Graphics' generateTexture. Features: - Paddle: arrow keys + mouse control, static body, immovable - Ball: circular texture, bouncing, collision with paddle/bricks/world - Bricks: rows of colored bricks, score - Lives, game over, victory, restart - Slight angle variation based on paddle hit position Write it carefully.

One bug: I reassigned `v = ball.body.velocity.setLength(newSpeed);`, but velocity is a read-only getter; setLength modifies the vector in place. Reassigning `v` to the result is fine (setLength returns the vector). But `v = ...` is declaring it with const... actually I declared it with `const v = ball.body.velocity;` and then did `v = ball.body.velocity.setLength(...)` — that's a reassignment to a const → TypeError at runtime. Fix: remove the reassignment.
Fixing one bug — I reassign a `const` variable in `hitBrick`:

Verify that the game can at least load without JS syntax errors. Can't easily run Phaser in a headless environment, but let's try a syntax check with node.
{"command":"cd /tmp/ws && node -e \"\nconst html = require('fs').readFileSync('index.html','utf8');\nconst m = html.match(/<script>([\\s\\S]Inline script syntax OK -rw-r--r--. 1 node node 9282 Aug 13 01:25 index.html

Also confirmed there are no external references: only script src is phaser.min.js. Good. If a headless browser is available, should I do a quick smoke test with Phaser? Probably not installed. This is enough. Done.
Done. `index.html` is in place at `/tmp/ws/index.html` — a fully self-contained brick-breaker built on the local `phaser.min.js` (loaded via plain `<script src="phaser.min.js">`), with zero external assets or network requests. **Features:** - 🎮 **Controls** — paddle follows the mouse, or use ←/→ arrow keys; click or press SPACE to launch the ball - 🧱 **60 bricks** — 6 rows × 10 columns, each row a different color; top rows are worth more points (10–60) - 🏓 **Angle-based bounce** — where the ball hits the paddle determines its rebound angle; ball gradually speeds up per brick (capped), and horizontal stalls are corrected - ❤️ **3 lives**, score/lives HUD, win & game-over screens with SPACE/click restart - ✨ **100% procedural graphics** — paddle, ball, bricks, and particle sparks are all drawn at runtime with the Phaser Graphics API via `generateTexture()` (rounded-rect bricks with highlights, circular ball with a specular dot, tinted burst particles on brick destruction) - Physics via Phaser's Arcade system, open bottom boundary for life-loss detection Syntax has been validated with Node; just open `index.html` in any browser to play.

EVALUATION
Fully functional brick-breaker with paddle, ball, bricks, score, and lives, ending in a working game over screen.
Vision grade · anthropic/claude-sonnet-5
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.
