I love the idea of constrained mazes like this. Another related idea is that of "plank puzzles" (http://www.clickmazes.com/planks/ixplanks.htm), which constrain available moves based on which planks you currently have access to.

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.

Sounds very similar to logic mazes (classic example for me is Theseus and the Minotaur)

…and for anyone wanting to try out more logic mazes, I suggest you check out one of the masters of creating them: Robert Abbott: http://logicmazes.com/

Yup, it's a very interesting page. I learnt about logic mazes there, after learning (and playing) Theseus and the minotaur. Just didn't want to add links to avoid sounding spammy (not implying that you do!)

One of the example solutions breaks the rule of "only pass a light once"

It doesn't say that, it says "twice in a row". This means you cannot half-turn and just go back the street you came from.
