3D Christmas Sled Downhill Game Builder

Claude Code builds an endless 3D downhill sledding game in Three.js for any browser. A streaming mountain with three biomes, ramps and air tricks with combo scoring, crashes with tumbles and slow motion, coins, gifts, magnet, shield and boost pickups, 4 sleds and upgrades in a shop, rolling missions, and saved high scores. Keyboard, mouse and touch. Every model and sound is made in code. A ?demo=1 mode plays itself for trailers. Re-theme it for any season.
