I made this puzzle following Scojo's prompt to make a squishdoku puzzle using the dutch flat mates constraint.

• Place a digit from 1-9 into every cell such that digits do not repeat in a row, column or 3x3 box. There are nine 3x3 boxes that overlap at the dotted lines.
• Dutch Flat Mates: Every 5 in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn’t need both.
• A digit in a circle indicates exactly how many circles contain that digit. That includes the circles attached to lines.
• Digits along a line have a sum equal to the sum of the two digits in the attached circles.
