I got permastuck on the 3rd floor - recovered the book and read the journal, yet there was nothing to interact with in the bathroom. Checked the browser console for errors, but there weren't any. Oh well.
The layered music is a nice touch, but it goes out of sync after a few minutes, probably thanks to the web build.
I would've loved some hints about controls, because it cost me a lot of mashing to find the keys for changing and closing open documents.
Good entry, rated highly.
