Happy Halloween!

I'd very much appreciate if you could also try this puzzle I made for halloween last year, which has still not got a rating:
Happy Halloween
or one of these which could use a few more solves as well:
There is an Apple in my Worm
Fletcher's Apprentice
The Digits Are Paid Actors
Merry Christmas
Whispering Worms
Or indeed any of my other puzzles! ;)

This puzzle contains quite a few tricky steps, which will likely be easier to see after some heavy-duty diligent pencilmarking.
Fun fact: my own test-solve took me 55 minutes. That did involve double-checking every single step to make sure the intended logic is valid, but I obviously did know what to look for. Make of that what you will.

Have fun!

Rules:
Normal Sudoku rules apply.
Adjacent digits along an orange Dutch whisper line must have a difference of at least 4.
Grey sequence lines contain digits in order, with the same difference between each adjacent pair. e.g. 1-4-7, 2-3-4 or 5-7-9.
Digits along a purple lockout line must not be between (or equal to) the values of the diamond endpoints, which have a difference of at least 4.
Digits along an arrow sum to the digit in the circle.
Digits in cages sum to the clue given in the corner of the cage.
Cells separated by a grey dot are either consecutive or in a 1:2 ratio (or both).
