Apply normal sudoku rules. Digits along grey lines (which cross) must be between the digits in their connected circles. Digits along purple lines have a minimum difference of 5.
I hope you enjoy.

I enjoyed this one a lot, thank you for sharing it. I don't think it's a 4 star difficulty though.

Edit: I just saw Mark did one of your puzzles the other day. Congrats!
Thank you for the offer, and I might take you up on it. I've had it up for 33+ hours and revisit it every once in a while. Maybe CtC will feature it and "solve" all my problems. I think your puzzle deserves it.

Even though I think I've broken into the puzzle's beginning, I think it broke me.
Still, I really enjoyed the artistic aesthetic and appreciate your time and effort, ___.
