Puzzlerium Tour: Yajilin

Rules: Shade some cells and draw a single closed loop through all remaining white cells, the loop's path moving horizontally  or vertically through cell centers. Clue cells may not be shaded. The loop may not intersect itself,  or go through a cell more than once. Shaded cells cannot share an edge with each other. Some cells contain a number and arrow, or a question mark, and may not be part of the loop. Numbered arrows in such cells indicate

the total number of shaded cells in the direction of the arrow.
