Difficulty: 3.5 stars

Really enjoyed this one. Liked how the solution path flowed through the puzzle.

Nice puzzle, although I got somehow stuck for an entire night by not seeing a cell forced to be used by an adjacent unused cell 🙁

For this puzzle type I find the penpa mode suggested to be too cluttered visually, so I used the yajilin mode which is better because the dots used to mark used cells are not visible once the loop is drawn. It makes the unused cells better too by shading them black and has a way to mark off edges.
