Daily League Sudoku #15: Difference Sudoku

This week I made a Difference Sudoku. I know I've made a lot of arithmetics-based variants. I think it's just what I'm most comfortable with. Just like I am most comfortable writing Loop genres when making puzzles.
I don't think this puzzle should be too hard. After last week an easier puzzle is probably appreciated. This puzzle has a simple opening and gets a bit harder in the middle, but nothing that should really break up the best solvers. Enjoy.

Rules for Sudoku

In this Sudoku, numbers between two cells indicate the difference between the digits in those 2 cells.
