Bart motors through the ruins of Springfield in the "Post-Apocalypse" level of the Sega Genesis version.
At a science fair, Bart wanders into a virtual reality exhibit and must pass all the "virtual worlds" (levels) to escape the machine. Passing a set of virtual worlds grants an ending sequence, and completing all the levels without losing all lives remaining wins the game. The format is similar to the previously released Bart's Nightmare, save for the lack of a hub world from which the levels are accessed. Gameplay for most of the levels consists of standard platforming elements. If the player runs out of lives, game over occurs.
Electronic Gaming Monthly scored the SNES version a 4.8 out of 10, commenting that "The control is awful (like on the dinosaur stage), the stages unappealing, and the whole thing seems rushed."
Reviewing the Genesis port, GamePro praised it as being "virtual identical" to the SNES original. They commented of the game itself that "The humorous variations on Bart, different game play (including behind-the-Bart racing and a shooter level), and cameos of Simpsons nitwits all combine to keep the action intriguing and funny."
