Thank you, sax^^ I will :)
I always try to make puzzles that are both visually pleasing and enjoyable to solve at the same time. Having only one rule with no lines or markings available makes it especially challenging to achieve both, and I’m sad to hear that this one felt AI-made to you, Sort. But thank you for the heads-up :) Even if it ended up as #93 in the book, this was one of my first Anti-Knight puzzles, and I hope I’ve improved since then. I hope you’ll feel more positively about the others :)
