This puzzle applies the concept of digits seeing other digits in a different way. I posted a simpler version of this puzzle some time ago, but I much prefer this version with its more challenging break in.

Rules
Standard Sudoku rules apply.
Adjacent digits along a green “German Whispers” line must differ by at least 5.
Digits in cages sum to the small clue in the top left corner of the cage and must not repeat.
Cells with a grey circle must contain an odd digit.
A digit "sees" all the digits in its row, column, box and cage. Every 1 must see exactly two 2s and three 3s.
