Tunnel Ball — the descent, enclosed
Tunnel Ball takes the rolling ball indoors. Instead of falling off the sides you now have walls, and instead of open sky you have a corridor that keeps narrowing.
How to play
Move the ball to line up with the openings ahead. The tunnel rotates as well as approaches, so the gap you found may not stay where it was.

Tips & tactics
01Track the opening rather than the obstacle — your eyes should be on empty space.
02When the tunnel rotates, move with it instead of fighting across.
03Short taps. The hitbox is tighter than the ball appears.
04Look deeper down the corridor when the speed starts to blur things.
About Tunnel Ball
Tunnel Ball is the enclosed cousin of the Slope run: same forward motion and instant failure, different geometry.
The rotation is what separates it from a plain lane-dodger.

FAQ
How is it different from Slope?
You are inside a tunnel rather than on an open slope, so walls replace falling off the edge.
Does the tunnel really rotate?
Yes, which is the main thing to adapt to.
Does the road ever run out?
No, distance is the score.
