The user wants a complete, self-contained Asteroids game in a single HTML file. Let me build this with: 1. A vector-based ship that rotates and thrusts 2. Ship wraps around screen edges 3. Shooting mechanics 4. Asteroids that split into smaller pieces when hit 5. Score tracking 6. Lives system 7. All procedural vector graphics - no external assets 8. CSS and JS all inline in the HTML file Let me write this out carefully to make it fully playable.

The index.html file has been written successfully. Let me verify it exists and looks correct.
The game is ready at **`/tmp/ws/index.html`** — a fully self-contained, single-file Asteroids game with: - **Vector ship** — rotates (← →), thrusts (↑), wraps around screen edges - **Shooting** — spacebar fires vector bullets with short trails - **Asteroid splitting** — large → 2 medium → 2 small each (procedural vector outlines) - **Score & lives** — displayed at top; 3 starting lives - **Hyperspace** (↓) — emergency teleport with explosion effect - **Pause** (P) - **Procedural everything** — vector asteroids with random vertices/jitter, exhaust particles, explosion bursts, twinkling star field - **Screen shake** on ship death - **Level progression** — more asteroids each wave No external resources, CDNs, or network requests needed — just open `index.html` in a browser and press **Space** to start.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Vector Asteroids game starts on Enter/Space, ship rotates and moves with arrows/WASD, asteroids and starfield render cleanly.

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.
