One Step Back is a 2D platformer that deals with the consequences of time travelling, where players have to guide their on-screen character to the exit without running into their other selves. For every few steps you take, another version of yourself will appear from the entrance of the level and retread the same path that you walked on just seconds ago. The current level resets if you accidentally touch any of your past selves, so you'll have to figure out ways to avoid them until enough time passes for the exit door to unlock itself.

There are nine levels to play in One Step Back.
