Shade Your Own Nurikabe Arrows
This is my first time setting a puzzle in about 7 months - this ruleset is one I've been sitting on for about 2 years but never really saw through to completion. Your feedback is appreciated! Enjoy :)
Rules
Normal sudoku rules apply.
Shade some cells in the grid such that all shaded cells are orthogonally connected and no 2x2 area is completely shaded.
All cells containing circles are unshaded, and all orthogonally connected groups of unshaded cells contain exactly one circle. Circles are arrow clues; each circle is part of one orthogonally connected path of unshaded cells, where the cells on the path sum to the circled digit. This path may touch itself, all cells in an unshaded group are part of the path, and circles must be at one end of a path (i.e. resembling standard arrows).
All cells containing squares are shaded and must contain a digit equal to the number of shaded cells seen in all directions combined (including itself), where unshaded cells block vision.
