As an outsider, my opinion may be way off base, but perhaps a reduction in the scope of the "minigame" contest to something that can be accomplished quicker, might incentivize more participation.
Rather than being a whole minigame, maybe it could just a small programming contest. Maybe it could just be an Enemy design, or a boss fight. Or perhaps a power-up implementation. So really, the focus is on small chunks of code that people may already be making or needing for their various fangames. Back when I was entering sprite competitions, it was always with the intent of using those sprites in a game. So maybe the same could be accomplished for these sorts of contests: program a class or two that could be used in a Mario game.
I'd love a contest like, "Implement FLUDD as a 2D Mario Power-up."
