What a lovely puzzle! I got stuck for some stupid reason (missing something which should have been obvious GW-wise). But even after I recognized my oversight, the puzzle held up some good resistance. So this felt like (at least) 3* difficulty to me. Thank you for this beautiful challenge, Rab3aron!
