Apparently, The Maw is already a fairly well-known game; it has been one of the "audience choice" award winners at PAX last year, as well as being a finalist in the 2009 Independent Games Festival. Check out the description, straight from xbox.com:
The pinnacle of alien evolution, Maw is a cowardly fat blob concerned mostly with snacking and lounging. He can, however, absorb the traits of anything he eats, is virtually indestructible, and can grow to unlimited size. If he wasn't a danger to all life in the universe, he'd make the perfect pet. In the action/adventure game The Maw, he's the best friend of our hero Frank, and only by working together, can Maw help eat their way to freedom. The Maw was honored with the Audience Choice Award in the 2008 PAX-10 showcase of independent games, and is a finalist at the 2009 Independent Games Festival for Technical Excellence.
Features:
-The power of The Maw: Feed Maw a variety of different creatures and make him grow to help get through levels. Use Frank's plasma leash to control the indestructible Maw, as he grows, evolves, and gains new powers that can be used to get rid of enemies and solve level puzzles.
-The teamwork of Frank and Maw: Frank and Maw must help each other to solve puzzles and get through each area. Frank's plasma leash can be attached to Maw as well as creatures and other objects to slam and toss things around.
Action and adventure: This single-player story-driven game features eight full levels with different puzzles and power creatures throughout.
-Musical score: The original music score was created by God of War composer Winifred Phillips.
Looks like its worth checking out; I don't know how good a game that has its musical score as one of the features can be, but its at least worth a demo run.
