The object of this game is to reach the door. In order to do that, you'll need to run, jump and... switch the world upside down!
1. Use the arrow keys to run leftand right.
2. Use the space bar to jump.
3. Use the shift key to switch the screen - white becomes black and black becomes white, so you can pass obstacles you couldn't usually pass.
4. Some of the levels have keys you need to get before you can pass through the door.
To start the game, click on SHIFT at the top of the game screen.
