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.
This was the first sgm i really tried, and I had one of the best solving experience I've ever had. Especially I enjoyed figuring out cuts below 450. Very nice find by kjs! I wouldn't be surprised if it goes below 430.
