Color Tunnel Game

Color Tunnel drops you into a Unity-built 3D tube that never stops moving. You steer a ball down the middle of a neon, ever-shifting tunnel, and the only real decision each moment is whether to nudge left or right to slip past whatever red shape is coming — a triangle, a cylinder, a hemisphere jutting out of the wall.

There's no map, no score multiplier to chase, no story. Just the tunnel getting faster the longer you last, and your reactions getting tested a little harder with every obstacle. It's the kind of game you open for two minutes and end up playing for twenty, because the moment you crash you immediately want to beat your last run.

Controls

• Desktop: Left and Right arrow keys (or A and D) steer the ball side to side.

Tips

• Steering is binary, not analog — small taps are enough to dodge most shapes, so don't overcorrect and swing yourself into the opposite wall.
• The tunnel speeds up the longer you survive. Expect the reaction window to shrink, and don't assume the pace that worked ten seconds ago will still work now.
