Had fun at it but remove one star because I had no optimization work necessary. The wrong routes I tried were too far from target to be plausible, so I jumped directly to next route and the first shorter one I tried was the winning one. I was like "oh, it's over?". A bit frustrating somehow. :D
Pretty good for a "totally broken level." Had me tricked for a little while. An unbroken version of this would be great, however. I really like the intended left side.
