The new version contains some important bug fixes:
The game had trouble saving some players' information, it turns out this was due to the fact that newer facebook user id's are much longer integers than older ones. Unity had trouble parsing them so I changed to code to handle them as Strings instead.
Some minor UI fixes were made, the UI now scales well for different resolutions.
A couple more custom ball styles have been added.
The new version is available for download now on the play at: Play.google.com
Any bug reports/suggestions are welcome! especially with regards the difficulty of the levels.
