I think this is a very solid concept and the graphical style in particular is very interesting and makes the game have a very unique vibe. There's only two things I have thoughts on that could be improved.
For the first one, the text in the intro was a bit hard to read due to the font used. It's important to maintain a good level of readability for the text, especially one in the intro that explains the story.
For the second one, I think that the game would benefit from more 'direction' at the start. Maybe just have a letter/note on the desk the player can read that explains to them the basics of the game with some more concrete story attached right out of the gate. I think it would help prevent people giving up on the game before they figure out the basic gameplay loop and get to the interesting parts.
Still, great job with this game overall!
