Puzzles like this make me wish I was better at sudoku, haha. The break in took me a bit and I had to play out the ending twice to find the correct wrapup. Lovely puzzle though!

I was stuck for 30min mid way not finding a logic step. Had to bifur twice. Maybe the logic was too deep for me. Lots of clever ideas in this as well thx.
