What tripped me up the most was when I was on the incorrect path, both left or right ways resulted in the same 2off stepcount so I figured it didn't matter which way I went. well it does when you get on the right path. Such a subtle but complex trick to save 2 moves.
6 off... will try to cut down the steps later. Really takes time to figure out how to breakthrough. edit: found a new way, but 6 off again... edit 2015: finally beaten, truly one of the best PP1 level!
edit 11-11-2022: I guess now I can appreciate a 2-off here, but the comments section help a lot XD.
I love duke PP1 levels. Always a nice trap or a hard to spot lock or a lot of ways to overthink a solution.
Particularly a fan of how some of the upper corner sections are designed here.
Years later, I come back to that one, not able to recall how I was doing to reach 2 off, and solved it within 10 tries... LOL! Again one where the trick is in the order we do things...
Took me 100 tries 2 start ''suffering'' from 2 off! :D Will keep trying though not much ideas left. Very difficult & interesting level. Edit 1,5 year later: found another 2 off & managed 2 optimize. Can't believe I got it. :) Wondering if the other one could be optimized, too ...
I was pretty shocked at the solution. I was stuck at 2 off for a while on a wrong path. I was so sure that the true path would be longer until I tried it. 109 tries.
Pretty tough: it took me fifteen minutes to figure out how to get through it. Not broken, I don't think, just closer to optimization. You will probably be able to find this route or better.
