Players control a geometric cube that jumps and runs through a neon world full of spikes, traps, and other things that can get in the way. Geometry Dash SubZero is a rhythm-based platformer. It's a spin-off of the original Geometry Dash game and has three levels that aren't in the original game: Press Start, Nock Em, and Power Trip. Each one has its own upbeat music tracks that go perfectly with the courses that get harder and harder with obstacles.
