Fractured Symmetry
Rules:
Normal sudoku rules apply.
German Whisper: Adjacent digits along a green line have a difference of at least 5.
Palindrome: Digits along a gray line read the same in both directions.
Little Killers: A clue outside the grid gives the sum of the digits along the indicated diagonal.
Kropki Dots: Digits in cells joined by a white dot are consecutive.
Happy solving!
Solution code: Row 7.

Super-cool symmetry and awesomely clever way to break it.
As discussed on YouTube, a few clues and the given digit can be removed, forcing quite a different solving path which leads to the same solution.
This alternative solving path is definitely harder, but fascinating.
I published these changes on LMD in a puzzle called Fractured Magnet.

Very nice puzzle.
Though, I got to the end of this puzzle and realised I hadn't used the 27 clue, nor the 28 clue on the bottom; I only needed the 28 clue on the right side.
I definitely used the Kropki dots, but not those two little killers.
I also think about 3 star. Still a nice puzzle though :)

This was a very nice puzzle, but I’d rate it more as a 2–3 star puzzle when using letters A–I instead of numbers 1–9. I also forgot about the 28 hints and didn’t need them.
