I must admit that I haven't looked at the Northanger Abbey code in so long that I don't entirely trust my ability to interpret it, but I think it tests whether the main character is a cis woman. Which is pretty narrow! I've actually been thinking of adding the ability to skip all the gender restrictions, they seemed like a good idea when I made the game but have ended up impacting the enjoyment of a lot of players. So you've given me an extra push in that direction!
