I tried to create an approachable puzzle with doublers. Have fun and leave a comment.

Rules

Normal sudoku rules apply.

Thermo-Difference-Lines: Digits along the blue lines must strictly increase from one end to the other. Every pair of adjacent cells on a line have the same difference. Different lines may have different differences.

Doubler Cells: For each row, column and box, there exists a doubler cell. Every digit must appear once in a doubler cell. Their value is doubled for the line constraint (not for the kropki dots). Additionally, all doubler cells have to be part of one of the lines.

Kropki pairs: Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
