The player controls Gravity Guy by tapping the screen (or pressing the keyboard space bar key on the computer versions) to switch gravity. The objective is to run as far as possible while avoiding obstacles that can trap the main character (who can be killed by a police officer), falling or flying off the screen. If killed, the player returns to the last checkpoint taken.
The three types of gaming modes in the game are Story Mode, Endless and Practice. Story mode features up to sixty levels for both "Run" and "Rescue", thirty levels for each part of the story, with up to fifteen levels in the original Flash game. Endless mode consists of running through randomly generated levels, while Practice mode goes through the levels from the story without the police officer. This game also contains multiplayer mode, allowing up to four players (using Game Center on iOS or locally) to play the game.
