In a beginning it was OK, but after that it all vanished. Very low levels required power ups. And when used, they are placed in worst possible places. As all of this kind of games, they want money and that is all!!!! As Kevin Campbell said (he commented before me, please read it) this game is rip off! Bravo Kevin!GUYS DO NOT PLAY IN COMPETITION GAMES!!!!! IT WILL TAKE ALL OF YOUR COINS AND BOOSTS BUT THE REWARDS ARE VERY PATETHIC!!
