iTunes Link: Doodle Jump
We couldn't do a round-up of iPhone apps without including a game, and there's no better one to mention than Doodle Jump. If you've already got it on your iPhone, you'll know what we mean. If you haven't played Doodle Jump yet, read on.
The object of the game is very simple; you try to get the Doodler as high as possible, helping him jump from platform to platform by tilting your iPhone/iPod touch from side to side. Along the way are various monsters waiting to knock you down, as well as exploding platforms and black holes to fall into.
Jump on the right platform and a rocket will send you soaring, or a pair of springy shoes will get the Doodler bouncing higher.
Of course, you'll have to get used to the odd strange look from people around you as you tilt your iPhone back and forth and sway from side to side desperately trying to get the Doodler higher.
We love Doodle Jump and really can't think of a better way to spend 59p. It's fun and addictive and best of all the developers at Lima Sky are constantly rolling out updates that keep the game interesting.
