Fantastic atmosphere and great art. I've enjoyed the puzzle quite a bit. Great narration for the first note, it really puts you in the mood and it gives you very settle hints to your next objective, but, i think the note next to the power switch didn't help me that much, it did at first but then i was automatically doing the next ones myself didn't need the note or maybe that was the point? haha.
Also the game didn't gave me the sense that i was making progress when doing the switch, i feel like something is missing there, a song? sound effects? i don't know what it is exactly maybe you've already thought about that for the full version.
I'm really excited to see what you can do with all the other items in the room.
Cheers
