I had big fun at solving this level. For me the hard part was at beginning, until I finally "saw" how I can possibly reach the target with enough blocks. Once that was clear, the fun kept going while optimizing the route, up to the funny "key" trick I needed to cut 4 steps.
Nice one really.
So funny! I had a good laughing upon winning. I never had a 2 off. I went straight from 4 off to winning.
The "trick" is for me totally counter intuitive! First time I see this type of "seems longer, is shorter".
Wow! That one was hard for me... It was in 3 episodes. 1st a route leading me far from target, until I finally saw a different one, that led me closer but still far, and at last another one, that brought me 4 off. With this one I had the feeling I can optimize it and yep, I cut the 4 shortly after.
Biiiiiiiig Fun!
