You are the small blue square on the bottom left. Use the arrow keys to move around. Do not bang on the walls, or you will go back to the starting point. If you go inside a portal, you will get transported to another portal. Reach the finish to win! New: There are lives in this as well. There are moving black lines in this maze. Make sure you dont hit them! There is also a rotating line later in the game. If you touch the purple, you get boosted forward. But rembember, too much boost is bad! And lastly, there are THREE portals. There are two in the upper maze. One of them leads to the next part of the maze, and one of them makes you lose three lives! The correct portal is usually the most accesible one, but not the way you're thinking....
Don't forget to play the other mazes!
