in the 6264 level there is a problem with calculating points, it is not possible to get the required lvl level, I can say that after watching the videos and after breaking this square, what the explosion does not count even 1 point
I guess there's a problem with scoring levels at the moment. I was having issues in another level as well. I reinstalled the game and it fixed the problem for me. A level i had spent days on turned into a piece of cake. :-) Hope that helps!
