It is pretty cool, I am not much of a VN fan but I can still appreciate what you did here. I think the main criticism I have is that sometimes the jaggies of the forground art can be a bit jarring against the background, maybe try more AA or make the art at a higher res? I really lime the music and some of the backgrounds are quite pretty. Keep up the good work!
Also: ignore the people giving you 0 star reviews and not even telling you why, their are a few people like that on every game
