This is a slightly more difficult follow up to 'A difference of 0 or 2'. I hope you enjoy it.
Irregular 6x6 sudoku rules apply. Place the digits 1 - 6 once in every row, column and bold outlined region.
If two cells are diagonally adjacent AND in different regions, then the difference between their values must be exactly 0 or 2. Eg. If R3C3 was a 5 then R2C2, R2C4 and R4C4 must all have values of 3 or 5.

Thanks for the series. Personally, diagonals are more normal than knights. Keep them coming.
