Mosswing · 3D tap-to-flap

Remaster the classic "tap-to-flap" game — the one where you tap to keep a small creature airborne while gliding through an endless series of gaps — as a 3D game playable in a mobile browser. One index.html, opens and plays instantly, no external assets (CDN libraries are allowed; your call).  Keep the core exactly as everyone remembers it: one-tap control, gravity, gaps that scroll toward you, one hit and you're done, score is gaps passed. Everything else is yours to decide: what the creature is, what the obstacles are, the world, the camera, the feel of the flap, how far to take the visuals. Design an original character and style rather than copying the original's art. I won't answer clarifying questions.  I'm judging a complete, elegant, great-feeling piece of work — not a feature list. Small and finished beats big and rough.
