Press the arrow keys to move the ball through the maze to reach the goal (green block). There are two walls that you can walk through (purposeful). The black block is a portal; walk through it to go to the second dimension. Walk through another to go back to the normal maze. There is also another ball that will chase you. If it catches you, you will be sent back to the start, and there is also a 10-second penalty. I may end up changing some things.
