The game looks great, but in my opinion, the story is lacking, even for an adult game. I think it would be better if you advertised the game as having a linear story too. Most VNs nowadays have at least a little bit of branching paths or somewhat relevant choices.
What threw me off is that I am not playing a game, I'm just reading a book. The images are pretty, sure. But the game makes you think you have a choice on stuff and that you can actually change something with the map feature, but no. It doesn't even make sense for you not to be able to save in the middle of a chapter, then. Idk, the choices you made when creating this just strike me as very odd.
However, those are a bit of a personal opinion. The only real criticism I can say is that the game doesn't have a strong plot and that it tricks you into thinking you can change something about your character when you first start a save. I spent almost a minute trying to change my gender, only to understand that it was only there for flavor. Besides that, it's an ok game with very nice art.
