Like everyone else, initially i gave it a 5 star review, but as of lately this app just got ridiculously greedy. If you aint got the money to buy power-ups then there is no way in hell you will win any event. And when they " the app creators/developers or who ever is in charge of the game", decide to give you power-ups as a gift, they give you like 15 pieces. REALLY!! 15 pieces. We spend more than 15 pieces in just 1 freaking duel, how are u really helping. Be generous and give us at least 250.
