Fantastic level! There are in deed 2 tricks to obtain the winning route: one is more a matter of finding the proper arrangement of blocks at a certain location, the other is a 2 off trick. The first one came fast for me, the 2 off trick got me fooled for a while.
(12 years ago) Very sweet level!
7 tries. Really interesting what shaves the 2 ... :)
