I made a few of them to test out how to best construct them. This was the easiest to come out of it. I figured I should first post this one for a change as a lot of times I introduce something new with a (too) hard puzzle. It's still tricky to solve because of the toroidal nature. Especially the deductions that span over the edges can be hard to see. But I didn't really see how to avoid that.
Rules for Yajilin
In this puzzle the grid is toroidal. This means the loop can pass through edges and come out on the other side. The clues also pass through the edge. This means each horizontal arrow sees the whole row and each vertical arrow sees the whole column.
