Interesting concept. Its like a beyblade spinners and over all implementation of rules is quite nice.
The type of combat can be really fun in local multiplayer pvp, especially on mobile.
Beating AI is a bit too easy, but its ok.
The sounds :D Glad you for adding mute option, but I was trying to be fair and play with them. They are simply too hard and stiff. I almost fall from my chair into ground when the music start at main menu.
