Nice puzzle, Richard! I definitely see what you meant regarding the synergy in the logic, compared to my puzzle. I am also surprised that this puzzle is rated less difficult than mine. My feeling was rather that this one is somewhat more tricky. Maybe difficulty standards have shifted gradually over the years?
@Jesper: No, I think another population of solvers. More all round puzzle solvers here compared to your Heatmap.
