This is nuts. There is an "end only" letter and a magnet in the low center of the board, just above three "rocks." By the time I get the rocks broken, the end only letter has magically disappeared, leaving only the magnet square in that little vertical alley. This leaves a gap where there are no tiles to spread the cheese to, leaving me with 4 spaces without tiles, so I can't complete the objective. I've wasted quite a few lives on this level and have to admit I'm stymied. I know I must be doing something wrong, but I can't seem to figure out what it is and how to play the level differently in order to avoid the same problem over and over, rather like the definition of insanity.
Any help or suggestions will be greatly appreciated!!
