Bug!

Bug! is a platformer released for the Sega Saturn in 1995.

Plot
Bug is a rising star in Hollywood, and the main premise of the game is it being an action film he's starring in. His family members are kidnapped by the antagonist of the film, the monsterous spider villain Queen Cadavra.

The plot is very basic kidnapping fare, but with a backset dropping of a movie set, which lends itself some unique additions to the gameplay.

Gameplay
Bug! is a 3D sidescrolling platformer that has Bug travel not only left to right, but into the background and foreground.
