The game uses a side-view perspective. Bart explores sections of Springfield and completes a different objective in each of five stages, such as removing purple objects, changing residents' clothing, or collecting items needed to disrupt the alien plan.

Bart can walk, jump, interact with objects, and use stage-specific tools. Progress depends on searching each area carefully, managing limited ammunition or spray, and learning enemy and hazard patterns. Some stages include a short bonus or challenge sequence after the main objective.

Search each screen before moving on, because useful objects and required targets are often placed above, below, or behind hazards. Conserve spray and other limited tools instead of using them on harmless scenery.

Learn the position of enemies and hazards through short attempts. In later stages, prioritize the required objective over exploration, then return for remaining items only when the route is safe.
