3D Santa Sleigh Delivery Game Builder

Build a full 3D Christmas game in ONE html file: fly Santa's sleigh over an endless snowy village at night and drop presents into glowing chimneys before dawn. Combos, naughty houses, owls, steeples, storm clouds, 4 power-ups, harder nights, synthesized Jingle Bells music + SFX, swipe controls for phones, saved high score. Change one line to re-theme it (witch with Halloween candy, cupid on Valentine's). Works with Claude Code, Codex, Cursor or any coding AI.
