Tunnel Ball

Tunnel Ball on Liftoff is the endless tunnel runner where a ball auto-rolls through a curved, forking passageway and you steer left and right to dodge obstacles and pick branches. The tunnel curves and slopes, so steering accounts for momentum, not just lateral position.

Speed escalates without cap. Early game is readable; later game demands pattern recognition because reaction alone can't keep up. Walls with gaps, barriers forcing lane switches, and blind forks repeat, and memorizing them extends your run.

The space-themed Liftoff site hosts it within its arcade collection. The core loop - dodge, branch, survive - is identical to other Tunnel Ball builds; the hosting context is aesthetic.

Distance is the score. Runs always end because speed keeps climbing, so the question is how long you sustain focus before a single lapse ends it. The personal-best chase is the hook.

Steer left and right with arrow keys or A/D. The ball auto-rolls forward through the tunnel.

Dodge obstacles by switching lanes. Walls, barriers, and gaps approach with a window to read and react.

Choose branches at forks. Some forks are safe on both sides; others hide dead ends needing instant commitment.

Survive as speed escalates. Early composure preserves reaction for the faster later sections.

Look ahead, not at your ball. Your position is peripheral; approaching obstacles demand attention.

Stay centered when safe. Center minimizes travel distance to dodge either direction.

Don't overcorrect. Sharp unnecessary lane changes into walls kill more runs than missed dodges.

Memorize repeating patterns. Recognizing them lets you pre-position instead of reacting.
