Such a pleasure to solve, everything was so intricately interwoven, yet still approachable for an intermediate ( at best) solver. Very enjoyable

The Battenburg negative constraint is surprisingly strong. Very nice combination!

Thank you for this beautiful puzzle, Qodec! The Battenburg constraint is very interesting. I have given 4/5 difficulty. But while being challenging the flow of logic felt so motivating that when I ever I got a little stuck I was sure to find another bit of logic that would allow me to move on. Thank you for setting and sharing!

Very fun puzzle to solve. I had never done a puzzle with a Battenburg parity constraint before. Thanks for sharing this!

Cool ruleset, with sudoku/thermo/parity logic all cleverly intertwined throughout the solve. Thanks for setting!

I suspect if I had done this while I was more awake and alert I wouldn’t have missed so many straightforward deductions, haha! Great fun despite my foolishness. Thanks for setting!

You couldn’t just proceed to battenburg the entire grid like that… that was such a cool puzzle :0
