The maze is surrounded by a poisonous swamp, and one hit will kill you - resetting you back to the Start Point.
Drag your finger around the maze to move the character's head. When you die, you reset to the Start Point and a gravestone is left where you died; helping you build up the maze as you go.
You can change the size of the maze in the settings, as well as the displayed character head.
Once you find the Exit, you can share a screenshot of the maze, with your death count, to social networks.
