The Lobster

Rules:

  • Normal sudoku rules apply.

  • Every line is both a Between Line and a Double Arrow. The different line colors are solely cosmetic as a way to help distinguish between each of the intersecting lines.

  • Between Lines: Digits along a line are strictly between the digits in the circles at the ends of the line.

  • Double Arrows: The sum of the digits along the line must be equal to the sum of the digits in the circles at the ends of the line.

Very nice flow, thanks for setting!
I initially ruled out more than you actually can, and it took me some time and a restart to wrap my head around the combination of the constraints, but once I got there it was a very nice succession of deductions.
Since I usually cannot solve a 4* for the life of me, I gave it 3*, but definitely one of the harder puzzles I've solved.

All the steps were very logical. After the different breaks, it wasn’t that hard, maybe a 3*
