Upfling gameplay: the climber mid-jump with an 11-floor combo running
11 floorsCOMBO
New best!

How it plays

Speed is height

Everything you do either builds momentum or spends it. Learn that in ten seconds, chase it for hours.

1Run, then jump

A standing hop clears one floor. A full sprint clears several. Bounce off the walls to keep your speed.

2Chain your combos

Land big jumps back to back before the timer runs out. The longer the chain, the bigger the bonus.

3Outrun the tower

The tower never stops scrolling. Every 50 floors it speeds up, the ledges narrow and the world changes.

Unlock them all
