I like this game very much, it's a great game. But the reason I'm rating it 3 star is because you have to play every level again even you get 3 star in order to unlock the tricks that are needed to complete the level. Please make sure that you will increase the reward so that you will not play the level again until unless you don't get 3 star. Another issue is that you should not think of getting coins wacthing ads because you don't get any because all the times it dosent show you an add fixthis
