This is my first Ludum Dare. My game gradually introduces and explores concepts and mechanics over the course of a dozen or so levels. Should I scale it back? Frankly the most interesting gameplay is at the end - should I be concerned that LD players won't make it that far? Should I just dump all of the best stuff into the first 5 minutes of the game?
