About Jump Up, Jerry!

Jump Up, Jerry! is an arcade platformer where you jump across platforms and avoid enemies to reach a high score. Its Score Attack mode takes place on an endless, randomly generated map.

Platforms and items

The cableway cars come in four types: falling, solid, jump-through and jumper. You can also catch four kinds of items: invincibility, +10 or -10 spikes speed, and -20 gravity.

Enemies and scores

Three kinds of enemies spawn randomly. Each attempt gives you 3 lives, and the game saves your high score and tracks scores on a leaderboard.
