The object of the game is to move the red block around without getting hit by the blue blocks or touching the black walls.
(Hint: initial move is down....maybe.)
If you can go longer than 18 seconds you are phenomenal. It's been said that the USAF uses this for fighter pilots. They are expected to go for at least 2 minutes! Trick is to think ahead and anticipate.
