The most recent update to Maze Escape allows for tilt/orientation control of the ball, smoother gliding along walls, and switching out your own pictures with the default picture of the ball. The speed of the ball seemed a little too fast, so I fixed it in a minor update. I plan to allow the user to adjust the speed and sensitivity of the ball in a future version. I may make the physics more realistic, too.
For now, look forward to saving mazes and looking at high scores.
