These illustrations are soooo beautiful! The atmosphere makes me constantly feel on edge especially with the added music. Really gives me Fear and Hunger vibes.
But I agree with Cody that some hitboxes could use some fixing. Some of the hitboxes on the bookcases and other furniture seem to be bigger than they appear. There's this one room with a (sort of?) transparent green door that I kept accidentally hitting and being transported back to the first floor.
The teleporting seems a bit janky and I think I got teleported outside of the map once, (but luckily able to get back inside). Also, the green text following the player seems to jitter as the player moves but I'm not sure if that's intentional?
Overall I think this is a really well made game! I had fun exploring the house. Great job!
