I have defeated the abomination, beat the game in 3033 turns.
Everything part of the game is cool. I like the instant movement and wall textures, the library is specially atmospheric, mysterious and oppressive especially in the big red book zone. I like that it feels super big with a lot of verticality (while also not wasting your time). I really like the structure where you advance through gaining hints, it was there but you probably missed it (spotting the key is very possible though I did not) is so much more fun than if you had to follow a scripted narrative to me. Exploring the red book zone before owning the teleport spell and wondering what I could do was interesting. The enemies and the big thing in the background at the end look cool and I enjoyed the fast combat, more than once (I mean I entered only 3 books so maybe twice?) I killed a minotaur when I was almost dead, it was tense. Smashing a crystal was a good way to end the game (rather than directly fighting a god thing).
This is a super fun entry, thanks for sharing.
