Not a lot happening in this one. I would work more on giving the player an actual gameplay related goal on the level. Also paly with players emotion, by placing some events (not neccesarily jumpscares). I liked the email in the beginning, gave me some Penumbra vibes. Also with the puzzles (keys), you could work out some more challenging solution, to make players feel clever when resolving them. Overall nice, but lacking entry, that could definitely be improved on.
