Caveman Jumper is a one-button jumping game set in a prehistoric landscape: your caveman runs forward and you press to jump the gaps, rocks and hazards in his way, with the pace rising as you go.
It's the simplest possible platforming loop, which is why it works as a quick break game — no menus, no learning curve, and instant restarts.
Hold the jump key longer for a higher, longer arc, and take off at the very edge of the platform rather than the middle.
No — it's an endless runner. Distance is the score.
Yes — tap to jump. Nothing to install.
