The game is 73mb, so not suprised there isn't that much content. It's like a lackluster version of
Flower Charm Sequel
Comparing this garbage with that amazing game is probably kind of insulting.
That said, I've seen games from this circle before, and they're usually just quick cash grabs with very little quality, and with their only selling point being the art... and that's assuming you like the artist in question and their style.
Between the restriction to one pose, barely any facial expression changes and the dubious quality animations... to say nothing of the nearly inconsequential training stats... this game is total garbage that isn't even worth downloading, much less paying for it.
I guess the girl is hot... but that's it and not worth the time.
Hell, one has to wonder if the time spent typing this is even worth it. That's how bad this game is.
