Highly enjoyable.
I found the backwards solving necessary to be quite confusing, but I pulled it off. It's probably a lot easier for those used to setting puzzles.

Great! Just need to know what corner marks mean and the rest is just wrapping your mind around working backwards.

Brilliant as usual - the classic sudoku you end up with at the end is also lovely to solve.

Very unusual logic that I agree is not too hard. 3 stars feels appropriate.
It is possibly worth explaining the meanings behind corner and centre pencil marking in the rules in case there are solvers who use different systems.

This puzzle is definitely worth your time and actually fairly easy once your wrap your mind around what you have to do.
