About Jump4

Jump4 is a platform game built around jumping with a single button. Each level has a set jump loop: pressing SPACE makes you jump according to your current place in the loop, and you can keep jumping until you run out of jumps.

Gameplay

You follow the jumping loops and manage your limited jumps in each level. Some levels are harder than others.
