A bit classic, but I enjoyed searching for the optimizations. I had a good laugh at the 2 off, because suddenly I won although I hadn't the feeling to have done something different... So not a clue what was the 2 off trick... LOL
I cannot give you criticism, cause I truelly think it is a very good level.
It took me 17 tries, and about last 5 - 6 tries I had troubles finding the 2 cut.
P. S. I also think SirDavid wrote a good review, from some other point of view. :)
