As soon as I saw the pig maze in Mumbo Jumbo's useless features video I knew I had to make that massive. And I did.
This project only took me a couple days, and it was incredibly fun! It's a 16 chunk maze, all 1 block tall, so you can't see anything.
I was also inspired by some wonderful Portal 2 custom chambers to make a multiplayer mode where one player has to guide the other through the maze. Don't worry- it shouldn't be much easier.

This is incredibly simple and not particularly pretty, but should be a bit of fun!
