Short and sweet! I like it. The visuals are really well done, the girls are very cute (kudos to the artist), the gameplay is snappy, and the pacing is really, really good. The mechanics are easy to understand and I am having a blast.
A bit of criticism is that the punches feel uneventful, and just feel like button mashing despite there are two buttons to it. I would hope there is a secondary mechanic of the actual fight so as to keep the game engaging. Also, for some reason, the gameplay (punches) don't have any sound effects at all, and felt a bit weird with how polished the other parts of the game are.
Anyway, this is a very cool and well-made game! Well done!
