What's required to unlock this achievement? I just completed every level playing co-op, and that seemed a likely trigger, but no achievement :(.

The level 3-7 show the white square, which the white player should end, but does not show the black square, which the black player should reach. My first thought was that the black square, for the black payer, was hidden inside the massive white currents surrounding the level, but couldn't find it....

Does anybody know how to get it? It seems to have something to do with passing in and out of 4 triangles, but I don't know which level.

Hi ! I can't lauch the game any more, I have a message saying some executable is missing which is weird because 15 days ago it was working. Is anyone met this problem before & could fix it ? I'm on mac Majove Thanks
