Cute. Nice art, nice boobs (and a butt). Feels a bit like a demo, but it isn't, it's really just a super short boss rush full of giant women with big assets.
Basically the goal is that with each boss, you avoid their attacks until a weak point (a flower) appears, which then you grab and pull, either pulling her pants down or pulling her top off.
(Obviously it's censored though, Jap dev.)

I'd say the only complaint I've got is that the first boss is really the only one that feels "done", as part of the tutorial is teaching you how to grapple onto flowers and swing on them to do some platforming, but that first boss is the only one that does it, and the game doesn't really even have platforming, you only use the grappling swing for dodging her second attack. The other two bosses just have you mostly standing around dodging some really simple patterns and you don't even need to jump at all.

Still, cool game, worth a try at least.
