Lima Sky has released an update to its popular Doodle Jump game for the iPhone and iPod touch adding support for Apple’s Game Center. In Doodle Jump, players use their device’s accelerometer to guide Doodle the Doodler on a journey up a sheet of graph paper, picking up jet packs, avoiding balck holes and blasting enemies while trying to beat other players’ high scores scribbled in the margins. The latest update adds integration with Game Center allowing players to compare their scores using Game Center’s online leaderboards. By popular demand the update also brings back the original doodle ghost halloween theme to the game. Doodle Jump is available from the App Store for $1.
