    Really liked this puzzle type ever since finding it on Palmer’s blog a couple years ago.

    And I think this is the first Castle Wall that actually looks like it could have plausibly been the wall of a castle. At least without the engineer getting beheaded.

    6:04 A very well-executed puzzle. The flow of the solving path was fairly evident, but at every stage I kept feeling like things were about to be underconstrained. Of course, I just needed to look a little closer and exactly the necessary information was provided.
