This game has potential but it's just so buggy. In game Options dissappear. Meaning you just have an endless queue of customers and no way to complete the level. You have to quit, losing lives and boosters. Ads sometimes have a black screen, again, forcing you to close the game, losing lives and boosters. I'll increase my stars when the game is actually playable. Playing more of the game. Play a level you need to serve 22 customer. Game provides you with 19. Pay up, or lose. Uninstalled.
