Vortex Survivors 3D Arena Shooter

Claude Code builds a neon-soaked 3D survivors-style arena shooter in Three.js: auto-fire combat, 4 distinct enemy types, boss fights every 5 waves, a 9-upgrade level system, orbiting shield orbs, particle FX, UnrealBloom neon glow, touch + keyboard controls, and a local leaderboard. All art and audio are generated in code — zero external assets. ~15 min build time.
