ARCADE BENCHMARK 04: Tunnel Tap. Build a complete playable browser arcade game as one self-contained index.html using Three.js. A craft advances automatically through a scrolling tunnel of shifting walls, gates, and safe channels. Use a deliberately small control vocabulary; reward reading the route ahead, clean central passes, and sustained combo play. Escalate through pattern complexity and speed, but keep generated routes fair and collision boundaries legible. Include keyboard and touch-friendly controls, distance score, combo, fail state, high-score display, and instant restart. Submit the final index.html only, not a mockup or explanation. It must run in a modern browser with no build step. Full design reference: https://gist.github.com/ponderingdemocritus/cf2b3f3933cadd06af9fe0e0c5aeabdd#file-index-html
