Whispering Caves

Rules:
Normal Sudoku rules apply.
Shade some cells such that all shaded cells are connected orthogonally by other shaded cells to the edge of the grid, and the remaining unshaded cells form one orthogonally connected area. Note that 2x2 areas that are entirely shaded or entirely unshaded are allowed.
Digits in circles cannot be shaded, and represent the total number of unshaded cells seen horizontally and vertically from that cell, including itself. Shaded cells block the vision.
If two orthogonally connected cells are both unshaded, then the digits in those cells must have a difference of at least 5.
Digits in cells separated by a white dot must have consecutive values. Additionally, one of those cells must be shaded and the other must be unshaded.
Solution code: Digits in shaded cells in row 8 (left to right), followed by digits in shaded cells in column 2 (top to bottom)

I love a good cave puzzle. Minimal clues in this one; some experience with how German Whisper constraints work in contexts without lines helped me here.
