Mineshaft Maze Layout.

I realize that this has already been posted, But I spent way too much time figuring out manually. Archiving for personal use in the future.

Updated that chest to the map. Truth be told I initially had that written down, But when I was making this chart I accidentally marked every subsequent room below the top left enemy as one row lower than it should have been. (So instead of the boss room being one to the left and four spaces down from the start, It was one to the left and five spaces down.)

Ended up having to shuffle the rooms back up, And I guess I just forgot to rewrite the marking.

There's a secret puzzle room where the farthest right Enemy is. It's a ladder that goes down.
