This will drive you nuts!! Have fun! The object of the game is to move the red block around without getting hit by the blue blocks or touching the black walls. If you can go longer than 18 seconds you are phenomenal. It's been said that the US Air Force uses this for fighter pilots. They are expected to go for at least 2 minutes. Give it a try but be careful...it is addictive!!
A tip of the hat goes to my friend Richard Sutton for sending this to me. File this one under fun and frustration; best I could do was a little over 5 seconds, so much for the friendly skies.
