      Thanks Sudgy — that was the key part of the solve I wanted people to discover, although it was a hard thing to telegraph so I was not how many people would find it.

    Fun puzzle! Proud that I found the sticking point from the solution video, though it still took me a while after that to find what it had unlocked
