Rook

Today's GAPP is a Marutaring with a brand new pzprxs implementation and a visual theme I definitely haven't done recently . . . It's not plagiarism when you steal from yourself, right?
I've included a GAPP 101 at the end of this post if you get stuck!

Rules: Shade some cells on the board to form a loop. Every shaded cell is adjacent to exactly 2 other shaded cells. Each group of shaded cells within a region must be a rectangle or square. A region may have multiple non-adjacent groups of shaded cells. Numbered regions must contain the indicated amount of shaded cells. Regions without numbers must contain at least one shaded cell.

GAPP 101: The loop cannot turn within a region if both of the cells adjacent to the turn are in the same region as the turn, because that shaded block within that region would be non-rectangular. Therefore, if you have a cell that would force a turn into cells within the same region, then that cell must be unshaded.
