So I finally played last (3 or 4) updates and... no change at all! At least in the "straight sex" path. With every single man Yoon acts absolutely slutty ("I'm such a slut" or "I'm so dripping wet" with a hobo she barely knows...). In a play, I even wait for the birthday party for her first sexual encounter in the game, but she still acts as if she already fucked every possible men...
The story of the first version (a shy Yoon and a slow corruption) with the graphics of the new one would have been a 5 stars game... too bad!
Yeah, this one ramps up fairly fast and now Yoon is pretty much a total nympho. The irony is that while I, like you, am a big fan of slow burn games where we build up to sex, if the burn is too slow many players start to get very pissed and pour hate on the developer. I think After Choices faced some of that with the first version, which I also really liked.
I think as a story, Free Pass doesn't make a lot of sense, but the art is good, the scenes are hot, and Yoon is so beautiful that I don't care. I even support on Patreon.
