Use arrow keys to move and jump. I made a little more "natural" scrolling simulation, with more natural movements.
Made a better version, with only one sprite needed, and credit to @PeaBrainProgram for the idea. Still need some work on it though. 10/22/14: oNE LOVE AND FAVE FROM @ penguinman3232 ! 11/6/14: Another love and fave from @Tr0mb0ne!
