Awesome. I ended up mapping out all the levels of maze as I played through the first time for future reference, plus I didn't know if there would be any backtracking involved and I didn't want to be up shit creek.
BTW, I think you're getting near the end of the game. There are only one or two more minigames (if that) and a final showdown battle with the evildoers (like the very first one in the game, but harder).
