Best I can describe it as is "deviant prison sim." I definitely feel it leans pretty hard in the simulation direction, with NSFW being just one part of that. Like, in a prison there are fights. This game just goes a bit further, and shoves sexual deviancy everywhere.

Huh. Okay. Well that might explain how the current route is "oriented toward subby people" when the game actually forces you to be dominant 90% of the time -- because apparently the game isn't about sex, just has sex in it.
Perhaps it's only because I'm playing the sexual deviant prisoner route that it feels like it's meant to be about sex. Maybe if I tried a different route I'd have realized it's just a prison sim with sex in it.
