A few quick tries later and I beat it fast enough to demote it to Masters. Great puzzle though! I couldn't improve on 2 off.
Edit: After a few more weeks I got it, the correct path didn't seem intuitive and the more obvious path was not correct. the obvious way is quite far off Stumped on this one but it's been fun working it out The solution seemed fairly non-intuitive and kept me searching for quite a while. Best levels ever made I'm not sure, but still definitely a 5/5. Very cool.
