I love it. The books are distinc enought that i actually didn't want to use bots, but eventually the other spells got too expensive to upgrade.
i'd say this is something you might want to explore for balance. If i want to focus on sorting things myself and not use bots then i might want other upgrades to be better.
The ui was in the way a few times, particularly the "books in hands" because the sorting goes there exacly and i can't even reach the bottom books, so had to wait for bots to fetch them in the end of the game. Made it in 118 mins while doing some work in paralell.
It was a tiny bit too easy. Maybe flip some books in the other dirrection or maybe even backwards so one has to flip them right before even seeing what book that is. And of course moooore books. I love that some are kinda vague, like songs of kings being poetry, maybe play into that even more.
Couldn't access music volume in game, needed to quit to main menu.
Over all lovely. I think i'd love to play that more.
