This puzzle is about hidden German whisper lines and I am quite happy about how this turned out. Feedback is always greatly appreciated! The rules are as follows:
Normal Sudoku rules apply. Each arrow points towards a cell on the boundary of the grid (i.e. the first cell the arrow "sees" in the grid). If the digit in this boundary cell equals x, then there has to be a straight German whisper line in the direction of the arrow (starting at the boundary cell) that contains at least x cells. Digits along a German whisper line must differ by at least 5. A German whisper line with 1 cell is allowed, but imposes no constraints.

strange that the 5s, which are so important at the beginning, are not found until the very end

Bravo! A refreshing set of new rules built on familiar logic, and cool to see it come together with so few clues. A favorite puzzle of recent memory. Thanks!
