Doodle Jump 1.13.3 update adds performance boost, 'triple-UFO attack'

Hit iPhone game Doodle Jump (claimed as the iPhone equivalent of Mario by the developer) has just received some loving from its developer Lima Sky in the form of a new update.

Included in the 1.13.3 release is a new monster boss, a triple-UFO attack formation obstacle, and the ability to jump on UFOs to take them down, according to Doodle Jump's App Store page.

It also looks like a few more easter eggs have been slotted in, as well as a better way to swap between themes. For instance, to swap to the night/halloween theme use the name 'boo'. Furthermore, iPhone 3G and 2G owners should see a bump-up in performance, and the ability to reset scores and statistics.
