Press arrow keys to move, there is no finish, so have fun twisting and turning! If you get stuck try going backward by pressing the down arrow key and then go forward by pressing up. You can also press the right and left arrow keys to turn your angle. It's a 3d maze even though it doesn't seem like one, you'll see!
