A really challenging puzzle, none of the individual deductions were overwhelmingly difficult, but they were consistent almost all the way to the end. Very nice. Thank you!

This is so well constructed. The way the geometry forces the solver to suss out the clarity is really something wonderful. The interactions are so rich. Brilliant puzzle. Thank you!

Amazing puzzle!
Even when you ask the right question and get the right answer, there are still more big questions to ask and it doesn't necessarily mean the rest of the solve will be a breeze

Very nice. It took me a little while to spot the implication of the math. But when I had the right thoughts, it flowed beautifully. Thanks a lot for setting and sharing.

Excellent! I never quite dare to believe that one can do such cool things with RSL, but you keep proving me wrong! :-D

Great puzzle. Felt like I was on the cusp of a break in for quite a while before I finally got there

Quite a brilliant puzzle. But smooth and fast if you ask the right questions at the start.
