I agree,

maybe it would be the best to build 3 maps which can be selected on startup. The game itself could be as you designed it then. You play your game on the map you decided to play on. Maybe (I don't know how map affect your gameplay) you could make one map for difflculty of the game (easy, medium, hard).

But this way you would be on the safe side with judging, if the judges declare maps as levels.

I also wish you good luck! And I also can't wait to play your game as much as all the other entrys.
