Well, except the ability to play it. Like other poorly conceived first-generation touch-based phone games, Earthworm Jim HD uses a virtual D-Pad that, frankly, doesn't work. Add some poorly laid-out buttons (seriously -- can you even tell what these on-screen buttons refer to?), and you have a game that is a total mess. Considering the precision demanded of a game like Earthworm Jim, this game is simply unplayable. If you manage to get past the first level without smashing your phone apart, you deserve an Achievement.
