Game type: Online flash game
Time demand: Each game tends to be very short. Very very short. As in, maybe a second, maybe a few seconds. Of course, you may or may not end up putting bunches of time into it as you try to better your score.
What it is: A simple little flash game. You click on a red square and move it around a small playing field, trying to avoid touching four moving blue shapes that continue to bounce around the playing field until the square touches one, and the game is over.
Short and simple, eh?
