Interesting level. I got stuck 4-off a year ago, but coming back now, once I rediscovered my original 4-off I found that cutting those last moves was not very difficult. Some decent optimization here, though I’m not too big of a fan of the level as a whole.
What a weird solution. There’s so many 79 variants of the same path, but that 77 seems to come out of the blue. Actually quite hard to spot. Very interesting indeed.
