The user wants me to create a single-page web app with a top-down alien shooter game using Phaser. Let me break down the requirements: 1. Single HTML file (index.html) with inline CSS and JS 2. Use phaser.min.js (already present in the directory) 3. Top-down alien shooter mechanics: - Move with WASD - Aim and fire at waves of aliens - Health system - Score system - Increasing difficulty 4. All graphics must be procedurally generated (no external assets) 5. No external resources/CDNs/network requests Let me first check if phaser.min.js exists in the current directory.

Good, phaser.min.js is present. Now I'll create a complete alien shooter game with: 1. Player ship (procedurally drawn) 2. Aliens of different types (procedurally drawn) 3. Bullets/projectiles 4. Health system 5. Score tracking 6. Wave system with increasing difficulty 7. WASD movement + mouse aim/shoot 8. Game over screen with restart Let me write the complete index.html file.

I've created the complete alien shooter game. Let me verify the file exists and has all the content.

RUN
EVALUATION
Game crashes on load with a JS error (setVelocity not a function), leaving a static unresponsive scene with no aliens spawning.
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.
- alien.setVelocity is not a function
