The game is created and maintained by a small company called Lima Sky, founded by two brothers based in NYC, Igor and Marko Pusenjak. Just like many other popular mobile games, Doodle Jump is very simple: You tilt your iPhone (the game is also available for Android, BlackBerry and Symbian platforms) and try to propel your character as high as possible by pushing off platforms.
Doodle Jump quickly became a huge success, appearing on many official top lists; Apple placed it second on the top iPhone paid apps list, and 10th on the top-grossing iPhone apps list.
Following in the footsteps of Angry Birds, another immensely popular mobile game, the makers of Doodle Jump plan to expand the game to more platforms and even outside the realm of mobile gaming. According to mobile marketing agency Appular, Doodle Jump will soon be coming to the iPad. (The tablet-specific version of the game has been in the works since summer 2010.)
A version of Doodle Jump for Xbox Kinect is also planned, and a Doodle Jump line of toys and comic book are also in the works.
