Nice 80 path.
Originally when I saw this level, I had no idea how to reach the exit.
Then I had the 82 and did not see any possibility to optimize further.
After I have painted the level in the editor, the way to do it became more obvious.
What a fantastic level! I haven't solved it, but it's a joy to look at and the concept is really creative. My 2 off feels optimal, but I can't find anything else faster than 7 off (lol)
EDIT: Ahhh, got it. Very cool solution!
