Gosh, I was loosing 2 steps, again and again. Had a feeling where it was (turns out, my feeling was correct), but still just coulnd't find it (for 112). Very GOOD level, IMO. :)
VERY interesting! First try I was just staring, not understanding HOW! Second try I came a few off. Next try I was 2 off. Then I read the comments and got it the next try. :) Often, comments somehow help me, though there's no hint. It's just some remarks, that ''let me know, what to look for or think about''. :) Very interesting, indeed!
Stunning level visually; the structure is impeccable. There's a neat observation that's required to get within a few steps, and the final 2-step saver is just divine. Lovely puzzle!
