Crazy level, definitely close to the hardest in the campaign. The path makes so much sense, but seeing it is incredibly difficult.
Edit: a month or so later, just re-figured this one out. Still a brilliant level and solution.
For me that was the easiest of the series. I was sure that one specific way to go is the only plausible one (other ways took me too far), so I focused on optimizing that one and won pretty rapidly.
Got stuck 2 off for quite a while, turns out the real path was completely different. I actually tried an idea like that right away but did it inefficiently... Great level set.
