hi everyone,

are the crossflip levels the same for everyone? it seems as if my level 556 is not solveable or as if something rather weird going on. i tried with and without keeping blocker tiles in the 2 matrices as zero rows. i tried with 2 of my own solvers and also via a well known public Z(2) library. all the previous 555 levels are no problem ... i can solve them within seconds each.

will look into it ... but as the library comes up with a solution i guess the matrix is solveable and the problem would be on my side.
