You’re a micro-man (whom looks like the same guy from Chicago Basement) as you traverse in some person’s digestive system. Why you’re in there, who knows? All you want to do is escape the slimy walls while tackling undigested food stuffs such as roast beef, carrots and potatoes. And there are bosses like Crabby Cabbage, Bad Bean and Bruto Broccoli.
You have a fork, but if you can find one, a knife will better your chances. Some levels are blocked so you may have to find a Gelatin Key. There are also replenishing junk foods such as cake and fried chicken.
