I was lucky enough to be on the correct route from the first. My 2 off was "only" a matter of ordering. Fun level.
Side note: in the ending zone, there are two different routings leading to 100.
I came back to this on and off sooooo many times. Finally cleaned this level away!
Amazing choice of close paths, I just kept choosing wrong ones that did not save.
This is GREAT! I had to try multiple times, with each time getting a bit closer. For sure took me over 5 minutes. Many options, how to remove the blocks in the way, had me confused.
