This is a 3x3x3 cube maze which means that the player starts of in one of 27 cubes and has to travel in all 3 dimensions, from cube to cube, to find the way out of the maze. The maze is also blind and gravitationless, which means 1) the player can tell whether the cube face that they are facing is a wall or a portal to the next cube (as would be the case in pitch darkness) and 2) that they can stand on any of the 6 cube faces and face in any of the 4 directions while standing on the cube face. The player moves from one cube to the next by finding the face with a portal and tapping the word "Portal". While in the maze there are random sounds and the maze has to be completed within 11 minutes and 6 seconds. The main challenge is maintaining a sense of direction and position in a blind gravitationless environment.
