Another Godot game! Great visuals and an interesting idea. Liked how developed your options menu was as well.
I found it a bit frustrating how (I'm guessing) the book could get caught on a shelf, causing it to drop. I often didn't notice right and had to back track a bit looking for it. The book pick up area was a bit small as well. I also found the game a bit repetitive and stopped after shelving a ~6 books. Is it just the one enemy? Did I miss some gameplay elements by stopping early?
Overall pretty solid.
