Navigate the mazes without touching any walls to get to the green box and progress to the next level. The red dot is guided by the mouse, so stay close to it. If the mouse goes too far the dot will drag behind. Don't let the dot touch any walls!
The reason for the dot instead of just the mouse pointer is because it prevents skipping over wall, which was difficult to get around until I programmed in the red dot. It creates a speed limit and moves a little faster if you stay right by it.
