It's really great that the game doesn't follow a shavemania contrary to the majority of the games that can be found here in F95. But, if you want more people playing rather than less, I think you should add the option at the beginning or on the game menu.
These assets that you have chosen for the characters have bene used in many other games. I think you could try to look for something a bit less known. This could add value to your novel. Right now the age of the characters seems to match with the assets, so if you change them you may want to pick something that will match as well.
There's something with the lighting that maybe could be improved? You could look into that... (e.g. Zeno's Anthology has it well made). I hope that helps. Looking forward to the v0.8
