Spacebar, Up Arrow, and Mouse Click are the three hotkeys that allow you to control your character in Geometry Dash SubZero and dodge the succession of spikes and traps. Depending on the environment and the sort of character you're controlling, pressing the hotkey repeatedly causes your character to leap or change direction. The user interface is straightforward, but this version's controls are a bit clumsy. Every route is fraught with peril and difficulty.
