A very nice puzzle! Just to add in my feedback as someone very familiar with irregular antiknight puzzles (since I can see a few people have struggled with this one) I found it fairly smooth with some very fun inactions, two star for me but I can see how someone less familiar wouldn’t know where to start. Hopefully this helps you figure out exactly how to rate future puzzles haha

Very impressive logic. Slightly frustrating at times but overall an enjoyable puzzle.

Very nice. Clever logic involved. Felt tough and I was making mistakes. Good stuff!
