heres an example of good touch screen usage For blobby world...
i use the touch screen to split (pull back blobby like a slibgshot)
to feed... (click on blobby) and to display the nickname, rank, leaderboard (in devtest that skips the naming and the leaderboard is ommited because there are no other cells in devtest... ;D )
