make no mistake: this is a NEGATIVE CONSTRAINT VX puzzle. everything else is just window dressing.
once you realize that, even beginners can do it.

Very much correct. One of the things I was going for was to have as few clues in the fog as possible. A negative constraint was perfect for that. Thanks for giving it a go!

Definitely 3* not that the logic is complex, but it takes a very long time to work it all out

I would probably call this a 3*.
I'm not the biggest fan of high value Little killers, but otherwise this was a fun and rewarding puzzle.

To be honest, I'm not a big fan of them either. Thanks for the feedback! I'm glad you still had fun.

Nice puzzle. Definitely 2 to 2.5 stars. Great logic and negative constraint deductions throughout.

Very nice fog debut! Fun solve. Not trivial, but not brutal. Thanks for sharing.
