There's been an accident in the slime factory and now it's up to you to clean up the mess. In each level you must collect all of the puddles of goo and direct them down one of the available suction vents to make it all go away. To do so, you'll have to push boxes out of the way and mind the arrows which allow you to travel in one direction only.

Plasma Worm is a free (until September 15th) downloadable arcade action game for Windows, and it is an evolution of the traditional snake-eats-the-pellet games that have existed since time began. The game pays homage to Douglas Adams, and the storyline (such as it is) involves the piloting of a plasma worm through a tank within the Improbability Drive, eating stray probabilities that could gum up the engine.

Another favorite of mine is this game by Squid S O U P. Snake delivers classic-style gameplay in a 3D Shockwave implementation. Very nice indeed.
