The Labyrinth of Minecraft

You know how to do mazes, right? Well, can you do it 4 different ways?

(Well you can't do it 4 ways, because so far there's only 1 mode...)

Well, the concept is simple: Get in, go through, use redstone, get out.

But there's a catch.

(On second thought, there's no catch yet, there's only 1 mode...)

So go through the maze!
