We're making a game with Game Center support called 'Chicks vs. Kittens'.
As a dev, I'm surprised there aren't more games supporting GC's leaderboards & achievements because it's been a real joy to put in compared to other SKUs such as XB360 & PSN.
How many balls can you catch? How fast can you move the paddles by tilting your device? Find out in Ball Catcher. Compare your scores with your friends scores with Game Center, if available on your device. Catch all the sports balls with your paddles by tilting your device. Keep an eye out for the red and green balls. Red balls will destroy one of your paddles and green balls will add a paddle, up to a maximum of three.
