I'm the guy who made that suggestion. I'm delighted by the amount of ideas people have thrown out about it--I think staying more or less within the confines of the genre, or needling at the boundaries (a little--but not so much that it wouldn't fit the jam, as Falcon mentioned above) is probably about what I was thinking of. The other interpretation I would have would be to go 100% unserious or even a bit trolly with the game, but as this isn't a trollgame jam, I'm hesitant to publicly recommend that interpretation :)
