I liked this level very much, but to be honest, I don't know why what I did was suddenly the right solution. Out of all routes I tried, I can't identify what is the 2 of trick with the winning one.
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!
