You know iPhone games have travelled pretty far when platformers actually work. This seems to be the case with Earthworm Jim on the iPhone, and while the controls were my worst fear, they have definitely been improved and revamped to work.
If you don't know what Earthworm Jim is, it's a platformer that has been on almost every "old" platform. From the SEGA machines to the Gameboy, Earthworm Jim has travelled a long way to finally appear on the iPhone. The iPhone version contains all new artwork and graphics along with some brighter visuals, but other than that, it's exactly how you remember it.
