It was also fun after the nice break-in!

Very nice break-in, not too hard but very clever. The rest is the job of the negative constraint.

Beautiful interactions in the break-in and pretty tricky scannings afterwards, still I found this one enjoyable to me :)

Outstanding puzzle! All of the constraints (positive and negative) worked together beautifully.
