Introduction:

Welcome to the Mad House. A comment from one of the CTC videos inspired this puzzle and the new line type. The creation of this puzzle got a bit out of control for what I'm used to, but "Howling Mad" isn't a descriptor of sanity, so I just went with it. This is also my first fog of war puzzle, so I hope this all comes together well. I also tried putting letters next to the lines to indicate what the lines are, to make the puzzle more accessable. Some letters I had to use best judgement for the placement, but might still not be perfectly clear.

Please send any comments my way.
