The goal of Doodle Jump is simple: get as high as possible. There's no real end - just death. The player takes on the role of Doodler, a little four-legged thing which constantly bounces off the platforms the levels of the game consists off. Of course the platforms aren't just neatly arranged so that the Doodler can blindly make his way up. Instead the player has to guide around the little fellow through the automatically generated levels by tilting the device in the desired direction. The gameplay is based on PapiJump.
Besides the constant threat of falling down either by missing a platform or landing on a platform that breaks on contact or explodes after a while, other obstacles await the Doodler. Monster (including bosses), UFOs and Black holes are a constant threat to the highscore. To deal with some of them, Doodler shoots stuff out of his nose when the player taps the screen making it possible to take out the enemies lurking above. In addition power-ups are available like the shield that makes the Doodler immune for a few seconds and various different kinds of speed-enhancers including spring shoes and a jetpack.
