Jumping Jack

Jumping Jack is about Jack, who is torn from his ordinary life and trapped in a strange world. With only an old pogo stick, he climbs through a mysterious dimension where gravity behaves oddly and the ground is unreliable. He does not know whether the top holds a way out or a greater mystery, but he must reach it to find out.

The climb

There are no saves or checkpoints, so one mistake can send you back to the beginning. Helpful elements can boost your progress, while traps can knock you off course. You need quick reflexes and careful thinking to navigate the unpredictable world.

Track your progress

A built-in speedrun timer and height tracker let you measure your climbs. The difficulty is designed to be punishing, with each hard-earned victory bringing a sense of accomplishment.
