The game is a collection of five interwoven "adventures", most of which can be played in any order. Each adventure has a specific goal, which can either be following an instruction or fetching an item. While you can earn points like in most other platform games by collecting coins, defeating aliens, earning cool items, etc., points are only for getting high scores, and are not essential to completing the game. All the adventures are a lot of fun to play, not least because of unique, fun items you can find and figure out the use for. The space aliens sequence (triggered by Bart's daydreams) and the basement action game are in particular very entertaining.

After Bart finishes all adventures, he can begin his greatest mission: saving his hero, Krusty the Clown, from Sideshow Bob. You will then guide Bart high and low through Springfield, searching for three cool items. When Bart has all of them (and has completed all the missions), he can enter the final level.

The game is by no means revolutionary as far as gameplay goes, but it features a lot of innovative variations on themes that fit well with the spirit of the show. For instance, the traditional health meter is replaced by a Cool-O-Meter (gauge from Un-cool to Cool), which measures Bart's coolness – something he really cares about. The game also includes many fun "extras", such as a VCR that you can use to fast-forward or rewind your adventures, and an option to change the game music (from Bart's stereo).

The only gripe I have with this fun game is that you must go back to Bart's room to save. This can be annoying if you are miles from his house, or in his dreams. Still, this minor issue hardly detracts from a very entertaining experience. Highly recommended for fans of the show, and everyone else who isn't afraid of the joystick. Two thumbs up!
