3D Voxel Road Crossing Game Builder

Build a polished 3D voxel road-crossing arcade game (endless hopper) with Claude Code: one offline HTML file with its own WebGL renderer and no libraries. Hop across procedurally generated roads, log rivers with lily pads and rail crossings with warning lights. Includes a fair seeded generator, storm pressure, coins, 8 unlockable characters, Daily Run, synthesized sounds, touch and keyboard controls, saves and a built-in self-test. Set the name, hero, theme, characters and colors.
