Cave / Stations
(Published on 12. December 2023, 18:15 by KNT)
Some cells are to be shaded such that all unshaded cells are connected, and all connected groups of shaded cells touch the perimeter of the grid. A digit not visited by the loop is unshaded and indicates the number of unshaded cells seen in all four directions from the cell containing the digit, including itself. All digits visited by the loop as well as intersections are shaded.
Along the loop, there may never be three shaded or three unshaded cells visited sequentially.

There is so much intricate logic at every stage. It has an extremely narrow solve path with each clue giving away only that much to take the solution forward. This is an absolute masterpiece. KNT is a setter who never ceases to amaze.

I've solved this thing like twice before this revisit and this time was just as fun and enjoyable - if not more - than previous two times!
Very well blended and carefully crafted solve path between different rules x)

Brilliant puzzle!
Great ruleset, which makes for a lot of very fun and interesting interactions.
Not too hard either.

Incredible puzzle. Never before have I spent 75% of my solve time convinced I must have broken the puzzle when I hadn't. Loved the way the different rules interacted.

@chalk235: the loop may not travel diagonally between cells.
