#129: Foggy Twilight Kurotto

After making the Twilight Kurotto for Black-out Friday, I figured these rules would also make for an interesting fog-of-war puzzle. You’ll have to solve this one in Penpa.

Rules: Shade some cells. White circles can’t be shaded. Number clues in unshaded (shaded) cells represent the total size of the orthogonally connected areas of shaded (unshaded) cells that share an edge with the clue.

Some clues are hidden and will be revealed by shading or unshading cells as you solve the puzzle.
