Reaction game for N900 to measure brain's reaction time

While working on improving performance of Puyo game, to bring some freshness to my mind I thought to divert my attention to some other activity, so I thought to create another simple game that helps to measure and  improve brain's reaction time.

Game will show you a blue rectangle at random place and you have to touch that rectangle within some time limit. If you manage to touch it than it increase your point. More  points mean better reaction time. If you get points more than 55 than it mean you have awesome reaction time.

If you want to download game and try it on your N900 then here is link.

Here are snaps from game.
