OK this game showed us something, and it is that the development of a game must be planned from the beginning long before even coding it, the story must already have a logic and know what content may or may not be present, make games with "routes "It is not easy, in fact it becomes complex and annoying for the developer since he has to make content for one route and then for the other and in the end nobody will be satisfied (it is already seen in other games), the decision to eliminate this content mentioned was correct, I do not mean the elimination of the ntr, but the elimination of 1 path to focus on another, for your first game I think it is better to do that, and regarding that content (and I know that This is not going to like many), I think I could add it not as a route but as an extra content (you already know some avoidable scene), it does not even require to be ntr as is (you know, the MC suffers, it is left aside and lose the girl), could be share (MMF include do to the MC), swinging with some npc and their partner, or prostituting a girl, I think they are less invasive options for some players, in addition to being extra and avoidable, no one is going to complain ... a lot
and they require less work than a full path.
Whatever the dev's reasons for doing this you have to respect them and let him work, if in the end you don't like his game (it's respectable), just ignore it and go to the next one.
