Excellent Vacuuming

- Normal Sudoku rules apply
- Yin-Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area is fully shaded or unshaded.
- Digits may not repeat in cages, and must sum to the value in the top left corner of the cage, if given.
- Cage totals indicate how many cells of the same colour (shaded or unshaded) are seen orthogonally from the position of the cell marked with a diamond in that cage, including itself. The 'other' colour blocks vision.
- Cells separated by a V sum to 5. Cells separated by an X sum to 10
- Every X and V lies on the border between the shaded and unshaded regions.

Yet another really fun entry to this series! The change to XV clues allowed for some new interesting logic.

Fun puzzle! Very cool how this mix of rules interact. I love how smooth it seemed deducing the killer cage totals entirely based off the yin yang geometry :)
