I reinstalled this game after a few years away from playing and I can't believe they changed the levels and made them extremely hard to pass. The only way you can get more than 10 Mins of game play is to buy boosters or extra lives. It's very disappointing. It used to be a fun game but it's gone to the extreme now. I'm only in level 355 and there is no way to pass it unless you have multiple boosters and you don't get the chance to create them every time on the level.
