The Jetsons: Cogswell's Caper

Cogswell's Caper is a side-scrolling action game where George Jetson can walk, crouch, and use a jetpack. Each level is littered with crates and other items that George can pick up and toss at enemies, while finding useful items (and enemies) underneath them. Since the game is set in the futuristic world of the Jetsons, there are also copious switches on walls which activate all kinds of features of the surroundings, such as a switch that reverses gravity for a brief time.
