A bunch of shapes are trying to knock you off the platform. You need to push them away without falling off yourself. Earn points for successfully pushing off an opposing shape, but if you fall off, it's game over.

This game can only be played on PC/Mac platforms with a keyboard, or on Android devices through sideloading. Use the arrow keys to move your player and the mouse to navigate the menu. Touch controls are also supported and can be enabled.
