Very Undertale. Much good. The Eyebat thingy's sfx when it flies towards you caught me a little off guard.
Would be Nice if there were time to dodge all the attacks. Wasn't much of a dodge window on all of them.
And I do feel like the bookless Eyebat + boar combination is harder than the book fight itself, which I think undermine the feeling of the book's power
But all in all, I like the little cat and its little story with the little cursed book.
