Hyper Tunnel

Hyper Tunnel is a browser first-person tunnel dodger. Your ship flies down a neon tunnel on its own while ring gates rush toward you; every gate is solid except one glowing open sector, and surviving means keeping the ship inside that sector as the gate sweeps past. Steer with the arrow keys (the ship orbits the vanishing point, so direction is what matters) or drag anywhere on the tunnel — the ship pulls toward your finger. Gates spawn every 0.55 to 1 second; the gap starts about 109 degrees wide and shrinks toward 66 degrees as your distance climbs, while speed ramps from 150 up to 430. Gap positions never jump more than about 137 degrees from the previous gate at the start, tightening to 86 degrees later, so every gate is always reachable — the challenge is pure reading and reaction. One point per metre survived; the run ends the moment a gate wall reaches you outside the gap.
