I really love the polish here, very nice touch with things like the music changing texture when going into the help screen (with the motif still seamlessly going on).
At first, I wasn't sure if my Interact was working since I didn't know I should only look out for glowing items. I was attempting to interact with the bookshelf and computer and nothing was happening, making me think my E was not working.
Once I walked around a bit more, it was obvious what I should be searching for.
Congrats on this game release!
