The background plot centers around the title character, Bug!, a famous Hollywood star hoping to make his "biggest break" ever. Players take control shortly after Bug! has signed up a deal for the lead role in an action film in which his girlfriend is kidnapped by Queen Cadavra and must set out to rescue her. The gameplay takes place "on the set" of each scene and cutscenes between levels indicate Bug! moving over from one set to the next.
Bug! was played like a traditional side-scrolling adventure game. In the same fashion as Sonic the Hedgehog , Bug! must jump and stung on the heads of his enemies to defeat them while making his way through large levels and collecting power-ups. What sets Bug! apart is the game's 3D levels, which take the side-view and tweak it. Bug! can walk sidewise up vertical surfaces and even upside down. Each set of levels (ranging from a bright, green grassy area to a deep red, desert level) has a deeply individual look and feel.
