I updated the link to reflect the changes that I made in f-puzzles, namely your (Puzzle Weasel's) request for the lines to be pale, rather than black.

Nice logic, thanks.
A small suggestion to improve the experience: the black lines you've drawn to clarify the arrow directions make it difficult to read candidates in those cells when using f-puzzles. Using a different (pale) colour for those lines would be better as then you can read the numbers which are drawn on top.
