Parity Little Killer Sudoku
(Published on 16. July 2020, 23:04 by Aspartagcus)
It's a (new?) variant on the little killer sudoku type.
RULES:
- Classic sudoku rules apply.
- Additionally, the numbers outside the grid indicate the sum of either the odd or the even digits in the diagonal in the direction of the arrow.
- Digits are allowed to be repeated along these diagonals.
Here is a 4x4 sudoku example:

Now for the real puzzle. One of the numbers has been explicitly indicated that it refers to the even sum.

Hope you enjoy solving it!
Solution code: Row 2 and 3 in succession, without any spaces or commas.

@glum_hippo: Thanks. :) Yes, it's a very simple constraint, but leads to quite some interesting setting possibilities. I'm working on another one at the moment.
I hope that not too many gave up because of this issue. I will let someone else test the next one before I post it. :P

Well the idea is terrific, and I do intend to try again.

Solved without the new clue (and with quite a bit of try and error), also don't see how that 0 clue would be immediately helpful.

It has come to my attention that there is an alternative set of digits in a diagonal that is possible, that I did not think of before, which makes the solution a lot harder to find.
Therefore, I have added another clue, which doesn't make the puzzle that much easier (it's actually still harder than I originally planned), but still lets you follow the solution path I've intended.
I added a 0 clue on the left side of the grid.
