Got this first try today coming back to it. Fun level. If you need a tip, this level falls under the category of: "the author was deliberately trying to hide the path" so reason your first steps accordingly.
I finally got that one, after long long time. What helped me now is that I was almost certain about the winning route, so I was focusing on finding the optimization trick on that specific route. With my experience from other boards, I studied it and spotted a possibility. It worked! :D
