Fun 3-D action-platformer where you play the persona of an egg named Charlie. The aim of the game is to go into underground city locations to repair broken mechanisms and throw a couple of switches to get things running again. Along the way, obstacles in the environment such as flipping platforms, billowing fire and a gaggle of enemy agents all try to halt your progress. Charlie's weapon is a wrench with sharp teeth that he can use to wallop anything that might get too close. Charming, with detailed locations to explore and interact with.
