Good boxing game if you don't mind the grind.

Best game I have played on android in a while, hands down. Its fun, intuitive, a bit grindy (but just enough to make it fun to play, not to point of frustration).

Coins take a while to earn. Costumes are character specific, and costume boxes go to random characters. It would be better if they weren't specific, or if you open a costume box, it was geared to the character you have set as your main.
