Earthworm Jim, brought to you by Gameloft (do these guys ever stop working?), offers the same terrific tongue-in-cheek sci-fi action as its predecessor.
As the titular mutated character, you'll run, swing, blast, and bungee-jump your way through 16 levels as you attempt to rescue Princess What's-Her-Name from the evil Psy-Crow and Queen Slug-for-a-Butt. (I didn't say it was a particularly sophisticated game.)
The onscreen d-pad control makes movement a little challenging until you get the hang of it, and it can be frustrating to miss a jump because you accidentally grazed the wrong part of the controller.
Even so, the graphics, sound effects, and gameplay are all here, making Earthworm Jim ($4.99) a worthwhile buy for nostalgia buffs and fans of platform games.
