Rules:
Normal 4x4 Sudoku rules apply.
Cages have exploded everywhere but are still linked together. Digits in a cage must sum to the given total and may not repeat. All cages have a given sum. (in other words, no other cages).
Digits may not repeat along the marked diagonal.
Solution code: Row 3

Great puzzle. There is also a unique solution to colouring the cage fragments assuming each piece ended up in a different box!

Really liked this! Interesting new logic.
Bordering somewhere between 1* and 2*. It's not that hard when you spot it.

If that’s a 1 star, I’m clearly in over my head.
Took me 50 minutes, and even then it was only because I finally decided I had to toss a coin and see whether I could find a contradiction (after going through 3 different possible permutations of the cages previously before I found one that worked).
Tough puzzle unless I’m completely missing something.
