Very fun puzzle! I had a strong start but found it quite hard even after making a lot of progress. Excellent setting.

Excellent puzzle, as I noted before. But also the symmetry break on this is theoretically interesting, as it is not wholly obvious and I haven't seen anything quite like it before.

I had to do some mental bifurcation, but the revelations were beautiful. Thanks for this joyful puzzle!

Needed an assist from Simon and friend, but very elegant. I love the sparse symmetry of the design.
