The 6 Weeks of Must Have Games is in full effect. Following on the heels of Hydro Thunder Go comes this week’s Xbox Live release, Doodle Jump. It’s out now on the Marketplace.

Doodle Jump is the progenitor of the jumping game subgenre. It distills the essence of platformers – jumping onto platforms, avoiding death by falling, and defeating enemies – into a simpler game. Here players control the Doodler by tilting the phone. He’s always jumping, so you only need to worry about where you’re going to land, collecting powerups, and tapping enemies to kill them.

The Windows Phone version of Doodle Jump (like Pocket God before it) contains the main game but loses a bit of content. Namely, a few themes are missing. Each theme changes the appearances of Doodle Jumper and his enemies as well as completely changing the background. Five themes are currently included on Windows Phone: Original, Halloween, Christmas, Jungle, and Space. For those keeping track, indie clone MonsterUp (similar if not better in quality) only has three themes right now, so Doodle Jump still has the leg up there.

Doodle Jump is a monster hit on other platforms. It’s extremely cute and easy to play. The Windows Phone version costs $2.99 and there is a free, short trial. Jump on it here (Zune link) on the Marketplace.
