Red Square
Instructions
Red Square is an incredibly addictive game to test your hand-eye co-ordination and speed. The object of the game is simple - you are the red square and you must avoid touching the blue blocks and the black walls. To move the square, left click on the mouse and keep the left button depressed and move the square to avoid the blue blocks, but beware they get a lot faster!
This game is apparently used by air forces around the world to test the skills of their pilots. If you can stay alive for 18 seconds you are doing well. 22 seconds and above is exceptional.
Unfortunately, I can't credit the author of this game, as I was sent the file via e-mail, but it's such a clever little game I had to include it.
