3D Voxel Adventure Game Builder

One prompt that builds a complete 3D open-world voxel adventure in a single HTML file: a hub town, 6 parkour courses with medals, a factory tycoon plot, races, an arena, hidden gems and chests, a story with daily quests, pets, 40+ cosmetics, abilities like a glider and grappling hook, building and a creative mode, touch controls and an autoplay mode for trailers. Works offline, ready for itch.io or CrazyGames. The demo was built from this exact prompt plus one short follow-up.
