You just gotta think, there will be rules on what you can and cant break, and what you can use to break them. I only have 1 maze, it isnt even that big.
Gigantic pillars of obsidian at different heights that you have to find you way across. BTW I'm doing something similar to this so if I think of anything else from mine I'll tell you about it.
I'm half way through it, and I already have both of those.
