Maneuver

So simple game principle and so tough to beat it. Using keyboard arrows you lead a square over other squares and one touch means, that the blue square disappear after you move away. The difficulty comes when numbers star appearing. These squares need to be visited more then once, depending on the number. Then you have places you cannot get on from one ore more sides. The idea is great but from the middle the game doesn't offer any new things and becomes a bit boring.
