A classic game of "Number go up", though that is by no means meant as an insult. I was almost reminded of Warioware and Rhythm Heaven of all things. I don't really have any suggestions on how to change this game up at all, if I had to suggest anything it would be that in the filling portion it's not really clear when the girl is getting too full? Having a separate face or audio/visual cue would be good, but it's not that big of a deal.
