Some tough but rewarding logic! The interaction was stunning and quite unexpected. I had a lot of fun with the parity and coloring logic.

Lovely and incredible puzzle! Deducing the parity throughout was like a whole ride to me; eventually I concluded almost 3/4th of the way but then pencil mark mistakes costed me more an hour to fix and finish this one :(
Still I enjoyed this one a lot!
