Great game but....

This game is great but there are some things I dont like in it. In the corner of the screen, it has a picture of a ball with a plus sign before it and there is a star that says free. But they cost 1-4 dollars! Thats ridiculous! Another problem I had is that the rankings dont show! Why?! Thats ridiculous! The last problem I had is that you need balls to play against other players! What if you dont have balls! Fix these things and I will rate the game 5 stars.
