The sound in Earthworm Jim may not be its crowning achievement, but it's still proficient. It may not be a musical tour de force like Super Mario Advance or Castlevania: Circle of the Moon, but the music never gets in the way and occasionally manages to be pretty catchy. The smattering of voice samples found in the original are included, though the tinny presentation keeps them from knocking your socks off like they did seven years ago.
