I remember playing this level for the first time, in 2009 and had to try twice. :)) It was the first level, for me, that did not go smoothly. :))) Such a pleasant memory. <3
It seems like a simple level to the experienced psycho, but some noobs are stumped by its trick. Some have found it so hard that they have started a thread on the forums for it. Minefield has distinction as the hardest puzzle with no moving parts.
