Uhmm where do I start, you put a lot of effort into the interface, which is not bad but in initial versions it does not feel very good, in my opinion I prefer a default interface, but with a greater development in the concept of the story, which at least it manages to be compelling.
The story is interesting, I will not deny it, but the MC except for being upset and betrayed, I do not even feel empathy for him, I mean, his only interactions outside the "professional" sphere are with the wife who cheated on him for self-interest, and even so the guy goes to the first one who calls him? I understand that it is a way to start the game and I don't know, but you can polish that, another thing, that personally bothers me, or rather makes me uncomfortable, all I have seen is scenes of lesbian "sex" dude, and the worst is that I have to swallow it with potatoes because I can not even skip it, and it does not even add anything to the plot, it only makes it slower and a little insufferable, with the story of the woman who fucked the grandmother of the blonde with eyes that seem to pierce the soul, it was enough and there was even excess, for the rest, honestly, the nonsense that of the shower, and that "because my father left, I started to fuck with his favorite student" they took away my desire to To continue playing this, the truth is, I like the story by itself, and I would have liked the same and even more, without the need for that kind of thing, and if you like the lesbian thing, there is no problem, for tastes there are colors, and each who has the right to like what they like, there is nothing wrong with that, but when you put something that you slows down the plot that already captures attention without the need for any sex scene, and even worse without the option to skip it, or choose another path or something ... as it discourages, you easily remove that scene from the daughter's conversation with the admirer of mc at the end of the beach together with that scene in the shower, and it suits you better, or already flat if you want them to have their interaction in terms of the exchange of words they had, to start talking as they have been doing in what take the story to, it was enough and you had plenty, what need to force that situation? And it is not out of anger friend, because as you happen, to hate your father's student, for calling your mother a whore (obviously, this without questioning if she ever asked her or is she aware that this daughter of her Demonic mother made her father before choosing to have that cut with him, which is understood but still something strange) to end up fucking with this mine, I mean it's absurd, friendship over there may continue but forcing a relationship like this nothingness, it doesn't seem a bit absurd to me. But good friend, it is your story, which is interesting and I see a lot of future for it, and I know that you will not be able to satisfy everyone with your decisions, be it in H scenes or in terms of the plot, but you can put options, or at least the free to jump or cut some scenes. You can perfectly make your story progress without putting a sexual scene, worth the redundancy because it is a VN for adults, and it would look good.
Personally I think that the story will be much better without what I mention, but that is my opinion, open who loves that scene, although it does not contribute a cucumber to the plot, but it does not mean that in my opinion I see it forced.
And come on man, give more love to the MC, that apart from the adulterous wife, we have to practically force ourselves to eat his interactions, there is nothing you can say that feels loved or supported, and how little there is interaction I am not counting it with the PE teacher.
Well, I think I go too far explaining my point haha, sorry if it may seem like I hate your job or that I could seem somewhat angry haha. Your story calls me interested, but in the same way there are things that, well, they take it away xD, and well your work is still green, it is in the initial stages, and I have no doubt, that if you could put together a story like this, you can polish and to enrich it in a better way, well, I better shut up that I already wrote too much haha, a greeting.
