The brief
Normal sudoku rules apply.
Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected and no 2x2 area may be fully shaded or unshaded.
White dots lie on the border between the shaded and unshaded regions. Additionally, white dots separate consecutive digits. Not all possible dots are shown.
Digits in caged cells show the number of cells of the same color (shaded or unshaded) seen orthogonally from that position, including itself. The "other" color blocks vision.
Adjacent digits on green lines must differ by at least 5.
