It worked smoothly on my Mac (Catalina 10.15.6). And I liked it!
I mean, of course I hope there could be more to it, but I know this is your test project lol. I liked your art style a lot and, for some reason, I think it's super compatible with VN as a genre. I'm no artist myself and English is my second, so I don't know how to put this feeling into exact words, but just say in my mind I can picture you creating a VN featuring 80s superhero comic style background, super villain daddies (with kinks), and twists and dramatic effects like it is in Ghost Trick (a phenomenal DS game).
... If that makes sense. Anyhoo I love your work and I look forward to your other works in the future!
