please let me know how you like the puzzle in the comments
Rules: normal sudoku rules apply however 9 may be substituted with 0 and it is up to the solver to deduce when and where.
normal kropki rules apply digits separated by a black dot have a 1:2 ratio (one is double the other). digits separted by a white dot are consecutive.
digits seperated by an x sum to ten digits seperated by a v sum to 5
digits next to each other on a green line have a difference of at least five.
digits with a gray circle are odd
Solution code: Enter row 1 (left to right) and column 8 (top to bottom) no spaces. 9 may be replaced with 0 if necessary

Very cool puzzle! I think this substitution rule has a lot of potential.

I don’t know if I did any mistake, in my solve path the grey circle was an unnecessary hint
The circle is so you can disambiguate that it’s a 9 and not a 0-Phire

Very innovative idea!
Suggestion: please specify that '9' should be replaced with '0' in the answer code if necessary
