Hi Watabou,
This game is one of the simplest rougelikes I have ever seen, but it still remains my favorite game of yours. But I have one idea.
Can you please add a difficulty counter on the final screen, like when you win, so you could screenshot it and everybody will know, you won on hard/medium/easy. And maybe add cause of death on the death screen. Thanks!
Also, there is a bug, if you read a book as a turn, and while you are reading, Librarian comes to a position, from where he should see you, he doesn't threaten you. So you can read a book, ignore the Librarian, make a move towards him, and only then he will see the character.
