This one has a great concept, but is poorly realized. If you think about it for only 1 second, clicking 4 times to make a square is totally unneccesary. The square could be already finished by 3 clicks, or, for bonus points, even with only 2 clicks by just clicking opposite corners. In this case you could receive bonus points. In the case you "misclick", points could be deducted as a punishment.
