How in the bloody world do you get the Tunnel Vision medal?

I assume that the medal is talking about the 'Mineshaft Maze' that housed Neon Valhalla (hated that boss with a blinding passion...) but i got all the treasure inside the rooms and out of the various areas in there. Is there another Underground Labrynith that I don't know about?

there are 7 chests you have to find in the maze itself, the puzzle room rewards do not count towards this.

And i just found the final treasure chest.... I hate that dungeon. Neon Valhalla killed me more than i care to admit, i forgot one of the treasure puzzle rooms and now this. That Labrynith is evil...

The trick is to draw a map on a piece of paper. But beware, if you encounter any completely straight rooms you have reached the edge, as crossing that makes you loop to the other side of the maze pacman style.

I didn't merely draw a map; I took screenshots of every single room and linked them all together in MS Paint until I got all of them together! It's not a 100% match to the map as displayed on the EBF Wiki, but it works!

Never heard of these games before, but started playing this recently and have gotten completely sucked in. So when I got to the mineshaft maze I had been playing for about 8 hours already xD Now I feel ancient these days so I cheated and just used the map on the wiki xD even then I almost missed one!
