Frustrating

At first this game seems great; great graphics and play. But as I advance it gets very very frustrating; all of a sudden my player never does anything right, and the computers player never gets anything wrong. At advanced levels the computers to player is everywhere, and gets balls from impossible places. I thought the shop is the place to my make my player stronger, the third item is outrageously expensive - it almost forces you to buy more balls to get the items. At the end I got so frustrated; I deleted the game from my iPhone.
