Puzzle 30: Crystal Mine

Here’s another Crystal Mine puzzle. I didn’t dare post this before the GP, worried it might spoil the GP puzzle. That turned out to be completely different, naturally.

    Two nice crystal mine puzzles, you’ve now made more than anybody!
    Interesting that we had quite different approaches to this type, my puzzle had no adjacent crystals which leads to a different kind of logic.

      Definitely easier to construct this way! It’s a fun type, very simple, I wonder how much can be done with it? With the Masyu-based presentation, perhaps some white circles (as not visited by the path) could help.
