Finally, an idea!
It seems like every year somehow the winning theme is one that almost everyone hates. I don't love this one, because it feels like we'll get a lot of really similar games, but I'd love to be proven wrong! It's taken a while, but I think I finally have a solid idea - I'm going to be adapting the myth of Theseus and the Minotaur. (I have been working on a project set in Ancient Greece almost all year, so it's on my mind a lot these days.) Surely maze generation isn't too ambitious for a 72-hour jam?
