(10 years ago) 6 close/far in 6 tries. But now? ... Huh ... will keep trying. :) Edit 1: 4 off in 35 tries. :O Edit 2: 2 off in 64 tries. *-* Edit3: More than 3 years later: not sure how or why, but with trying I got the 176 path. 222 tries, on the nose.

EDIT 2023, 7th May - rebeaten this ''L'' thing. :) This time I understand better, though still not COMPLETELY sure. Giving 5 stars, now. It was not easy (for me). :)
Found 2 different ways to do the start... tried to look for 174 but I think 176 is optimal. It took me quite a while to figure out how to get to the exit.
