I deleted this game. Bombs/boosters are inconsistent in their effectiveness. Not here to spend money just want to play while waiting at doctor's offices but as you get higher in levels there are more extreme and hard levels to waste all your lives on and I'm not purchasing anything to get past a level. Can't even enjoy the specials because it takes so long to get through a level. Some "normal" levels are just as impossible as the extreme. I'm done with your game.
