VI : Whispering Nurikabe
Normal sudoku rules apply.
Divide the grid into a number of islands -- orthogonally connected groups of cells. Every island contains a single circled cell; the digit in the circle indicates the number of cells making up the island.
The islands are surrounded by a waterway -- a single orthogonally connected group of cells. All caged cells are waterway cells; the digit in a caged cell indicates how many waterway cells are seen orthogonally from that position, including itself (island cells block vision). The waterway cannot form any 2x2 areas.
On islands, orthogonally adjacent digits differ by at least 5.
The given 8's are island cells; the given 5's are waterway cells.

Amazing interplay between all the constraints until the very end. Really well done. Definitely trickier than the other ones I've done in the series, but very satisfying.
