What a wonderful puzzle. About to watch the feature on CTC. Took me three tries to finish but I made it there in the end. Cheers!

That was such a beautiful and smooth solve! The heyawake twist in the rules really made this puzzle feel incredibly fresh and added some really interesting interactions throughout the entire puzzle! Thank you for sharing :)

Cracked it! That was superbly elegant and sufficiently challenging for me. But I'm rather proud to call this my first Heyawake solve.
Thanks for taking your time to set this, and thanks for answering my rules question so thoroughly.
