I spent 90 mins sorting 2990 books and all I got was a measly letter! I'm sure there's some universe out there where the books all started pre-sorted to make speed runs super fast, I think I just need to keep resetting the map roughly 10^9096 times - it will be sorted eventually right?
I would play again if there were another stack of books but this time they all look the same and you gotta open the cover to know which column and row they go into, and the books move around randomly. >:D
