This time I'm back with a really idiot level: it's a 15x15x3 maze made on a 15x15 level...
I know, I could have done a nicer one using a bigger map and the teleporters, but since I was set to "timewaster" as default from the factory, I did it using some CEs, three sheets of paper and a lot of patience!
It seems a very though work, for me, but I believe it could be done. Maybe using a big map, where the three floors are created separately and then merged together.
We'll see, Tomi, to be sincere I've done it just for fun
