On: Viennese Mazes: What They Are, and How to Make One

[BWStearns]

Very cool puzzles and nice to share the code.

One thing about the example mazes/solutions. On the hard one, isn't tqp-khe-bdc-a a faster solution to the hard one listed?/Doesn't going t-r first violate the red light rule?

You are reading it backwards, you must start in (a).

The old holding the map backwards mistake. /facepalm

Thanks for letting me know though, my brain went with starting at the bottom for some reason rather than the letters.
