Finished it! My honest opinion was that it felt like a pretty small scale VN, people got i, got out, found out a plot twist and that was the end. It was so short that it didn't really stick to me too much. Which is especially damning for a VN because they live and die by their ability to grab the reader.
I do think that the art is actually fine though! It's simple but it definitely gets its point across fine and is no real point of disdain from me
