Normal Sudoku rules apply. Additionally:
1. XV XV: cells separated by a V sum to 5; cells separated by an X sum to 10; cells separated by an XV sum to 15. No negative constraint.
2. X: digits along the main, marked diagonals cannot repeat.
3. Little killer: clues outside the grid indicate the sum of the cells along the marked diagonal.

Another lovely puzzle Thoughtbyte. I really enjoy the flow of your setting.
@ddurschlag, I’m colourblind, so the CTC app functionally only has seven colours for me (silver, grey, black, yellowgreen, bluepurple, orange, and red). But I used the drawing X/O function to differentiate individual digits in pairs.

Made me wish the CTC app had more/worked better with colors!
