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.
Enjoy!
Solution code: Column 9, top to bottom

Hardest rated puzzle i've done, but loved every minute of it. :)

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*
