I really have nothing bad to say about this game. Subjectively, I find it to be a near perfect game.
But there is something I would like to say. From my point of view and in my opinion, of course.
Maybe it's my impression, but I find the sexual scenes not very dynamic or varied. I'm not talking about fetishes, or anything. Obviously I won't say all of them, but I have the impression that most scenes follow the same pattern: The MC making dirty talk, telling the girls that they are his personal little sluts and he loves to fuck them all over their holes and the girls only confirming it.
I'm not saying this is a bad thing, just that a little variety might be nice. There may be times when the MC and the girls fuck because they are horny and there some good dirty talk makes sense. But a little more romantic sex, where the girls are more sentimental about the situation they live in and want some affection and it shows that they are really in love, might also be okay.
Like I said, it's just an impression I have. Maybe it's not like that and it's just me, but well. That's the only "but" I can find. The rest, as I said, seems almost perfect to me.
