Pretty sure this is a known bug already, but the back button doesn't work and there is no way to exit the game.
Works on basic level on S3. Will play later today and give better feedback!
The Commandments of Android
1) Open RAM is wasted RAM - Don't use Task Killers
2) Cheap devices are cheap for a reason. Don't expect high end performance.
3) Boot Loop = Wipe.
4) There are no viruses for android.
