Please check out my latest os project, Crofts Cheetah. It features an intuitive user interface plus the ability to import your own music, pictures and backgrounds. http://scratch.mit.edu/projects/Mrbus/2329960 This addictive, fun and simple arcade game took me a few hours to make. How to play: Left and right arrows are to move sideways. If you have an android tablet or touch screen display you might prefer to use the touch controls in the bottom corners of the screen.
