Having played the free version, I will agree with most people's complaints about there being too many characters/branching stories, the MC looking a lot older than what his age is supposed to be, and there being no sex scenes. Personally, I don't mind the no sex scenes early on. I look at this story as a "slow burn" type of story where more effort is put into the story telling than the action. Some other people have mentioned that some of the female characters look ugly, which in my opinion, I disagree with. I think there's a wide variety of types in this game and I feel like the older women actually look their part in here unlike most VN games.
I personally think that this game has a lot of potential and a great foundation, however I feel like there are too many game mechanics/characters/stories to follow that people might get burned out. I would love to see more of this game and I'm worried that this might be too much for a small dev team to tackle.
