Are you a genius? Are you fast? Can you keep attention in the screen for some seconds? You can't! Press the screen to shift to either a square or circle and matching the incoming shapes.
Challenge the impossible, challenge yourself, and go as far as possible in this really cool, hard and addicting game!
With the same principle of Guitar Hero, here you need to click as fast as possible and to continue playing. It's a great game to test and improve your attention, perception and brain. All you need to do is to type the screen as faster as possible.
This game is part of a tutorial, you can check more about it on http://bytedebugger.wordpress.com/
