Glass Maze is a maze app using the iPhone accelerometer, a precision physics engine, and openGL 3D graphics. Tilt the iPhone to roll the ball to the exit, and try to improve your time for each maze size.
This free version includes a random maze generator, and the player can now select any maze size from 6x6 to 18x18. The rolling-ball mechanics can be changed from the normal setting to a slow-moving low-gravity mode, or a definitely-not-slow "madball" mode.
