when you mention other levels, do you mean "once you beat the king it turns out he was a figurehead and you have to go take out shadow dictator Santa Claus" or "when you start the game you select between "roughly English speaking locale" and "the north pole""?
i could have just said "linear progression or level select" but "shadow dictator Santa Claus" is one of the funniest things I've ever written and I'm not letting it go to waste.
