This quirky title from YoYo Games takes the simple 2D side-scroller and turns it on its head—literally. The topsy-turvy gravity lets you hop from platform to platform without fear of falling down, which sounds easy until you spot the spikes and constantly shifting surfaces that make getting through the game’s 80+ levels a real challenge. Cute, simple animations make reaching your goal—feeding yourself to hungry, blob-like monsters—all the more enjoyable.
