I think the concept is good and the potential yuri novels in her collection are fun to figure out, but the execution of the concept is pretty rough. The controls aren't great. There are a lot of pain points when it comes to doing actions, like having to use enter to advance text, despite being a mostly mouse operated game. Additionally, the act of identifying books at Patchy and then saving them for later is super annoying given I don't have any good place to organize them other than back where they were. I think this concept would benefit greatly taking on another form, maybe something like Diner Dash where you don't have to do this jarring transition between screens. It feels like the correct way to play this game is burn a bunch of runs just identifying the specific books and what preferences the individual fairies have so you don't have to spend so much time fumbling over giving them to Patchy. Again though, I really like the concept and the different books are fun, it's just hard to interface with.
TLDR: Concept with fun writing and lots of potential but hard to interface with
