Babelium
Babelium is a roguelike set in Borges’ Library of Babel.
It’s still under development, so this is just a beta version, but you can walk around, read the books, and explore the infinite variety of hexagons.
And the entire game screen is a valid page of a book from the Library of Babel. You could, in fact, play this game by flipping to the right page in the right book off the right shelf from the infinite library.
