After my review, the game completely stopped working. Uninstalling now. Dropping stars from three to zero. Does get too hard when you get to the levels where you have to clear many targets and there are not enough moves. You go through all your boosters and hope to beat it before getting too frustrated and just uninstalling the game. I've only done one save the king, which is the main reason I installed this game. The life counter is a nuisance. If there are over 150 levels it isn't needed.
