(seven years ago) Good level, was about 6 off, took me 21 tries to find the shortest way. :) Edit: Manti, gr8 find! Took me some more tries. :D

EDIT 2022, 22nd Oct. - I rebeat it and adding stars, now. :)
First 3 tries were 8, 4, then 2 off, but it took me a while to find the final 2 cut. I feel like manti's review is a bit deceiving... I was looking in the wrong places for optimizations for quite a while.
