Try to avoid touching the orange rectangles for as long as possible. The longer you survive, the higher your score. To jump, press the space bar. If you need to jump particularly high, then press the up arrow as this will allow you to jump twice as high as normal. If you lose, then you can restart by typing 'yes' in the resultant answer box. Type anything else and the game will end. Make sure to have plenty of Friday physics fun!
