Ok here is a few resources to help you out
1) In the Ged , the game is made in iphone resolution .
2) Its fully functional game with onscreen buttons.
3) Graphics done by me , so you can use them in your work.
The goal of the game is to jump over the barrels and collect the coins. Very fun game using onscreen controls.
Take a look at the code so you can see how basic buttons are done. Plus highscore feature!!
