Absolutely wild opening. No idea who is rating this 4* or anything less than very nice :)

Whow, this was a crazy puzzle. It started by me staring at it infinitely, making no progress (it might have been 1-2 hours of staring and trying stuff to no avail). Absolute despair, it just won't start. And then, after trying again and again, I finally found the break-in, and from there it was a quite smooth, maybe 3.5*. Overall, very beautiful puzzle and solve, but one has to get over the Hump of Despair in the beginning.

(Another puzzle with the same Hump of Despair first then really beautiful progress from there, is LieScrapers by Marty Sears. Similarly, I had to stare for an hour before making any progress.)

I hate antiknight, and this puzzle was no exception. It was so good I did it anyway.

Fantastic puzzle. Not sure if I followed the intended path but the logic worked very well even if it was far from easy. Thanks!
