After clicking the blue dot, your goal is to click the green circle at the end of the path without touching any of the red. Touching the red will send you back to the starting screen. Beating a level will send you to the starting screen for the next level. After getting to as level, you will be able to go to it in the level select. Clicking while in the maze and not touching the green circle will send you back to the starting screen, to prevent cheats.
All of this was done by me, and I might add more later.
