Great puzzle. Had some trouble with the disambiguation at the end but was able to figure it out. Thanks for the puzzle.

this wasn't too hard, except that I couldn't spot all the anti-knights, so it was very hard. either way it was a great solve, especially the disambiguation at the end.

Loved the disambiguation of the coloring at the end using the dots! Fun puzzle!

Very nice colouring puzzle, definitely feels like the harder end of 2 stars/easier end of 3 stars to me

More of a 3 star than a 2 star to me. Very fun!
