I loved the artstyle a lot. My favourite part - is how the lights swich turns the room dark gradually.
I noticed some parts are loading (pictures on the laptop and books) but when they are loaded once the next time they are loaded much faster. I actually kinda liked the loading speed when they are loaded slowly the first time, that creates this "internet" effect :) for the books I would keep the loading speed consistent every time they opened, but for the laptop pictures I would add some randomness so it would keep that "loading from internet" effect.
Edited: btw, I have 16:10 laptop and the game works perfectly fine on that resolution 👍
