An evil wizard transformed Prince Jerry into slime and stole the princess! Jerry must ooze across land, sea, and beyond to restore order in this platformer that features clever jelly mechanics. You can walk and jump, and holding X or Y lets you run, jump farther, and stick to walls and ceilings. DOWN attacks by squashing outwards, UP headbutts enemies from below, and if you jump on foes, you can ride piggyback until you crush down on them.
