I don't know if anybody else found the word "either" in the puzzle rules a little confusing, but I guessed (correctly) that it didn't mean that with each cell we had to work out if the cell that couldn't contain the same digit was a Knight Move or King move.
Other than that minor confusion, I found this delightful!

Really cool puzzle, but nowhere near a 1* - solidly in the 2-2.5* range.

a miracle sudoku with ZERO given digits.
very nice, but there are a couple tricks in there that put it beyond level 1.
