I left feedback on the worst bits: I said this layout was "Unintuitive" and i want to expand on that: the most obvious route was never the right one. The points were instantly obvious from the start, but then the routes to them were usually oddly-shaped, and forced you to go around the back too much. Flanking routes at A and B took you so far past the point i twice missed B entirely and had to double back.
Plus, the Chokepoint between B and C was horrible, you should never, ever, ever, ever, ever ever, have only one route between places.
