Have yet to figure out the trick to get the last two moves.. had more trouble with this than a few of the \"hard\" levels.
After 168 attempts, it earns a 5 in my eyes.
Sorry for all those who beat it, but there was a hole. If you found my intended route the first time around, it should be no trouble to beat it again, otherwise good luck!
Real challenging one! First the right path has to be found and once so far, it must still be optimized by finding out the proper order to do each step of it! 3 points only?
