Caught me out making assumptions right from the start. Had to go back and start again before I could figure out what I'd done wrong. Great fun.

Beautiful puzzle! The whole time I thought I was way out of my depth, but again and again the next piece of logic revealed itself elegantly. Thank you for a tremendously good time!
