I was able to eliminate a lot of potential shortcuts but there are still so many paths that get you close to 383. After a break I finally had a new idea of what could be faster and it ended up being the correct path. Amazing level.
Got it on first try, because before to start, I noticed that one directional block is placed in such a way that it could be the key to a major simplification. I tried it and I was right. It was the winning route. Fun!
