I LOVE this type of games. The soundtrack fit really well too and gave the proper ambience for this.
The puzzles weren't too hard but it wasn't too easy either, really impressive for a game jam. It's easy to make things too obscure or too simple. It was immersive reading about gravity in the book.
For the author puzzle I struggled with missing one "a" letter. Probably just a me thing from understanding who you meant and then remembering the name wrong :P
I struggled the most with finding the down/floor button for the tetris piece. None of the other rooms had that and the colours are so monotone I missed it. I mean such is the nature of point and click games that you may miss stuff like this but just thought I'd point it out. (Maybe have clearly contrasting buttons if you think this a problem?)
So far my favourite game in the jam! Loved playing it!
