The art was pretty good, and the story was interesting and took a surprising route.
I felt that the visual novel part could use some more user input, however, as beyond the point-and-click part and one option near the end, there didn't seem to be much player control. Even just a dialogue option that shows some flavor text would add more interactivity.
I'd also think addition of back/history buttons could be beneficial, in case the player misses something,
I noticed, while most of it used two colors, one part had many grayscale colors on screen at once in the background, presumably from some sort of blur effect.
