Overall, this is a really good VN, and I want to point out the good and the bad that stuck out to me the most. If I don't mention it, then you can believe my impression was good.
James - I very much enjoyed how involved this other guy character got involved without being a sexual interest for the protagonist. I don't think these types of characters get the love they deserve from Devs, usually feeding us a line of forgettable extras. Giving him the responsibility of conquest over one of the sexable characters was a nice touch too.
RL Plugs - There are real life topics injected into dialog, which I think was done tastefully, and helps out with immersion into the story, even a little background politics.
Realistic Dialog - Every conversation feels like a conversation people would actually have in real life. I really like my immersion.
No Soundtrack - I'd say no soundtrack is better than a bad or bland soundtrack, but it still would have been nice to have a little mood music. If you're not TERRIBLE at it, mood music is a pretty potent mechanic for keeping a reader engaged. With the clear amount of effort put into everything else, I have little doubt you could nail this pretty good too. Did I mention my affinity for immersion?
Price - I'm sure you feel pretty proud of the handful of enthusiasts that have been happy to pay the $15 for the full package, but you might not realize that for every person willing to pay $10 for an ebook/visual novel, there's four to five willing to pay $4 for the same product. If there were a limited number of copies for this VN, it would make sense to charge enthusiast prices, but the nature of digital property, it can be copied infinitely. I'm going to pay the $15, because I'm an enthusiast and I'd like to support your future projects, but you might consider dropping the price if you'd like to see a bit more capital.
