All you can do in the game is take the ball, approach the goal, and be disappointed by the wall in front of the goal letting you know that you cannot score, nor be scored against, without making an in-app purchase, and therefore cannot finish a game. When you go to make the in-app purchase, it does not tell you how much it costs, and when you try to load it, it just ends up loading endlessly without getting anywhere. So basically, you can do nothing without making a purchase, and you can’t make a purchase. Honestly, if they’re going to charge you for a game, they should just be upfront about it and not put it on the App Store as free.
