I did find the opening a bit hard, probably didn't find the right one, made a combination of a couple of candidates and together they worked. Pretty smooth from there.

Lovely! I managed to spot the break-in very quickly, got completely stuck in the middle for good 50 minutes only to facepalm at how easy the next step was, and then it was over. Very cool puzzle :)

Nice setting. Didn't think it was hard, but that's probably because I'm getting better at this method too ;)
