Dev has been gone for longer than the whole development cycle of the game at this point. I think it's fair to see they abandoned it, though sometimes devs come back months later
We got people complaining about NTR in a real-porn based game, how dumb is that? How does it differ from the real porn scene it was taken from? If that bothers you then all porn, minus solo POV, is NTR since you're not doing the fucking.
It's simple: the porn actor is not in a relationship in real life (at least not with me), but the character she "plays" in game, is. Some freaks might consider any random person having sex with anyone but them NTR i guess, not sure how to break to them that most women they walk by day by day are NTR-ing them frequently.
