What a level! Seems kind of forced but it was still very difficult for me to get rid of the last 4 moves. After several tries came to 2 off and then 2 tries more brought me to the exit on spot (144).
Finally got it - this one was tough! Splendid solution. It was hard to keep track of what I had already tried, but in the end this path does make a lot of sense. I really enjoyed playing this level :) There are some very interesting ways to be 2 off as well.
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...
The way to the goal is fairly complicated. I had great great trouble and was very far off despite repeated attempts 7 years ago. It is interesting that I always have a great sense of achievement beating duke's levels. haha :D
