The usual for me: I struggle to solve the 2 off and when I solve it, I have difficulties to understand why this specific route spares 2 moves compared to the tries before. It looks like I will never be good at pipelining... :(
I was 2 off since more than a year. Today, I come back to it and I solve it on 2nd try... Can't believe it somehow. :D
Levels with lot of freedom like this one, with lot of different routes coming close, are always very difficult to me. Am happy!
