I personally didn't like it, I liked the way the story was going up until the point where the NTR starts... I was expecting something like the "enemy" starting to fuck your girlfriend in some way you didn't know, hence why letting you see part of the bedroom where your girlfriend sleeps, but at some point in the game it forces you to cheat on her... And I really didn't liked that because I didn't felt the NTR anymore, but I tried to ignore that, since in general I was liking how the game was going, so I tried to give it another chance and keep playing it, thinking that maybe that was the only situation where we was forced to "cheat" but it wasn't, we are forced to do it again and that's when it killed the game for me... I didn't feel the NTR anymore because the MC was unfaithful to the GF so I really couldn't care if she did the same now, you know? So that's when I stopped playing it
And I also think it's kind of annoying going around all the map looking for the next thing to do in certain situations
I think the sex scenes in general are hot, that's a good thing
