You need to get to the exit, press shift when hitting an exit or a switch. On the normal control setting you must rotate the ball with the left & right arrow keys and jump with space. On the other control setting the arrow keys change according to the gravity, if the gravity is down it's left and right, if the gravity is right is up and down etc. You can change the controls in the menu.
