Sludge Crawler is a side scrolling video game for the PC. It's about a gelatinous blob who has run out of soda in his house. He must go to the grocery store to pick up a bottle of soda. On the way there, there just happen to be enemies and weird places that are unavoidable because his world is 2D. The game features an original soundtrack by James Iarocci.
Powerups in Sludge's world are clay molds that re-shape the blob to change his abilities.
