aa is actually a genreless game which we've decided to call a casual puzzle but which feels more like brain-training exercise. It challenges your fast reflexes with a simple premise: a big circle's rotating clockwise or counter-clockwise and you have to tap little dots to attach them while avoiding touching those that are already attached. Straightforward, right? We'll see how far you can get!
The game concept is original. Touchscreen response is excellent. The difficulty of the game increases gradually. It includes online leaderboards where you can submit your personal bests.
It can be boring after a while. Different game modes, unlockable achievements and extra items would make it more challenging.
