Symbiote by Skeptical Mario
Rules:
Normal sudoku rules - Place digits from 1-9 in each cell without repeating in a row, column, or 3x3 box.
Digit sharing - For each cell, the value of the digit in the cell is split evenly among each clue (dot or line) using the cell. For example, if a cell containing a 6 is bordered by two dots and crossed by a line, the cell counts as 2 for each dot and the line. (This split value may be fractional, but only whole numbers may be entered into cells.)
Kropki - Cells separated by a white dot contain values that differ by 1.
Cells separated by a black dot contain values where one is double the other.
Not all such relationships are necessarily marked by dots.
Region sum lines - The blue lines are divided by the 3x3 box borders into segments. For each line, the values in each of its segments sum to the same total (different lines may have different sums).

Tricky but interesting puzzle. Lot of neat deductions resulting from the digit sharing.
(Which also caused me to mess up my maths quite a lot in the second half of the puzzle, which was definitely a lot harder)

Really an underrated puzzle overall, but quite tricky for me in the later half!
Once I marked those particular cells in proper notations, it's a lot easier to consider the cases and the observations, and I especially liked the usages of one certain trick on region sum lines throughout the solve :)
