I have played to this great puzzle for a total of 3 levels. It seems difficult. It needs to complete all the equal squares between them and to end the first level. There are the bombs that serve when you are already in difficulty. But attention to waste all the bombs, because the game ends.
I have made only the first level to score 8,560. I have not succeeded in completing the second level.
