The fact that you can place any digits at all in this grid is astonishing. The fact that this SOLVES is absolutely freaking bananas. The fact that it not only solves but is smooth and enjoyable from start to finish and keeps presenting novel and satisfying logic throughout is, pardon the cliche, nothing short of a miracle. Incredible work.

Easily one of the most impressive puzzles I've seen. Incredibly minimal grid, and yet the solve path is incredibly smooth and uses all the clues brilliantly throughout.
I have no idea how to you'd even begin with making something like this.

It is astonishing that this puzzle a) exists, b) solves so smoothly and with beautiful logic right to the end and c) was found by you. Incredible puzzle cogito, I don't know how you found this, but it's immediately one of my all time favourite puzzles.
