3D Platformer Game Builder

One prompt that builds a complete 3D platformer adventure in a single HTML file with three.js, with a new twist: a bell flips every level between day and night, so star bridges appear, enemies wake and secrets change. A hero that's a joy to control (double, long and wall jumps, ground pound, ledge grab, swimming), a smart camera, a hub with 6 levels and 3 bosses, every star proven reachable by bot routes, Time Trials and a Photo Mode. Includes 20 bonus ready-to-use idea sets. Try the live demo.
