I've never left a review on steam before as far as I know and I usually don't feel the need to, but I just noticed this game only has 10 reviews on here at the moment and that seems CRIMINAL to me.
This game is an absolute steal, one of the most premium packages in the yuri and erotic VN scene with beautiful presentation, excellent music, gorgeous art and that's not even getting into the content of the game itself. The amount of extras that come packaged with the game is wild too, you get SO much bang for your buck with this one.
The actual content. All seven of the main routes, while I haven't done each one yet, features interesting characters from what I can say given the introductions and cross appearances. Unlike most dating sims/romance VNs, after the prologue you select your route straight up (presentation here is immaculate) and lock in to a completely unique scenario. The game has a really great balance between erotic scenes and truly heartfelt ones, Natsuki's really touched me (and she really touched me too) and the sex scenes are pretty light but well written and for me, more palatable than the usual H-game fodder. This is more similar to a game like Ladykiller in a Bind, where it feels like it was actually written for lesbians rather than guys who get off to them (though I'm sure it'll please the himedanshis)
Also, it has butch x butch, which is a rare and beautiful thing they do absolute justice. I only wish we got more...
