To start the game click and hold the square in center of screen. The aim of the game is to move the square around the screen without touching the wall or getting hit by any of the blocks and walls. It's been said that the US Air Force use this to test their fighter pilots. If you can go longer than 37 seconds you are phenomenal. Give it a try but be careful...it's addictive!
