So, I'm about half an hour in, some critiques:
The renders are just fantastic. Some of the best I've seen. Really well done.
The font and color are frequently difficult to read. Darker color and a more standard font would be best. Especially when the screen is lighter and the text ends up bleeding into it.
You need a copy editor. Seriously, you need someone to look over your script/text and fix mistakes and correct grammar. There are mistakes in nearly every line of text in the game so far. If you like, I'm happy to do it for free. I've been a professional copy editor in the past, can give you links to some of my online work if you're unsure. If you don't take me up on it, at least find someone who can do the job, because the VN seriously, seriously needs it. Your text is not doing the renders justice.
