It was rather a consistent solve for me, but the interactions between different clues were a lot of fun to figure out :)

Tough but very elegant. A few times I got stuck, but I eventually asked the right questions and found it fair.
Solution checker relieved a lot of potential frustrations for the few times I wandered off the solve path.
