The camera rotates whenever you press the left and right key, giving the illusion that the actual maze is rotating. The gravity of the level is based on the camera, so the ball will always be falling downwards. My game has a limited view, so that you have to find your way around the maze and cant go straight to the exit. The end goal of all the levels is to make it to the exit, which moves you to the next level.
My game has 3 different levels, with the last level being more of a puzzle than a maze.
