    I stumbled my way through the first 30% or so and then it took pity on me and solved pretty smoothly from there on out.

    Hi Paul, thanks for solving 🙂 Yeah, the opening steps are mostly where the difficulty is. I hope it was still enjoyable. Cheers!

    Recall this being very difficult for a good while. Notes say 18:38. Faving because it is just such an inaccessible-looking grid that does go places in the end.

    7:07 due to a few careless mistakes. Abused a certain technique commonly found in masyu puzzles (which I shall not name here) which, interestingly, also works in deformable masyu.
