I haven't played this enough to write a review, but my first impressions are kinda disappointing. This feels like a kinda early beta rather than a finished game. If it was unfinished, I'd feel I'm being overly harsh writing this, but as it seems to be done...
The character creator seems powerful in places but clunky. Character-side looks like it can go pretty deep but isn't particularly easy or quick to use. Clothing is a bit more limited - a lot of the cosplay costumes aren't made from in-game tools but specifically-made costume textures. That said, it seems easy to plug in your own custom clothes, if you're up for doing that.
The fighting is... somehow floaty and clunky at the same time. Just punches and kicks flying wild, sometimes connecting, sometimes not, and doesn't seem to be connected all that much to the actual model. Not sure if there's any combos or anything, couldn't find any. Didn't find any grapples. It's not particularly hot or competent. Clothing gets destroyed as you go through the match in a really unsatisfying way; I'm not too surprised considering how wide the creator is, but it's still a tad disappointing.
The H seemed weirdly customisable but also kinda flat and boring to me. Seems like you get one scene after the fight and a bunch of options with regards to how undressed the girls are/how happy or unhappy they are, but the animation feels a bit stiff and honestly not all that erotic.
So... yeah, kinda a disappointment. The character creator might be interesting if the fighting and H was worth it?
