What if we included the theme in some not obvious ways? Like, the whole game is actually something wicked, but we never let the players know it's actually this(You know, like pokemon would be about Ash being in a Coma or Link in Majora's Mask was actually dead throughout the entire series etc..). You know, we hint it's there but we let the players guess if it's like this or not.. Is there a way to let the judge know what the underlying thought of the game is, without informing the playerbase what the game actually is about?
Sorry if I don't make sense, English isn't my native language!
