Implemented a level selection system with 5 difficulty modes (Recruit, Pilot, Captain, Commander, Test), each with different asteroid counts, sizes, speeds, and constraints. Upgraded BabylonJS from 7.13.1 to 8.32.0 and fixed particle system animation compatibility issues. - Add card-based level selection UI with 5 difficulty options - Create difficulty configuration system in Level1 - Fix explosion particle animations for mesh emitters (emitter.y → emitter.position.y) - Implement particle system pooling for improved explosion performance - Upgrade @babylonjs packages to 8.32.0 - Fix audio engine unlock after Babylon upgrade - Add test mode with 100 large, slow-moving asteroids - Add styles.css for level selection cards with hover effects 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
