The player (as Gumball or Darwin) must break out of detention, collecting three stars in each level while platforming through the Elmore Junior High hallway as Miss Simian and Principal Brown watch the character over the surveillance system. The player can take advantage of the camera frames by using them to teleport into the opposite camera. When the character reaches the door, they must press the spacebar to advance to the next level. Obstacles such as spikes and patrolling robots appear as the player advances through the levels, as well as more complex puzzles (such as anti-gravity puzzles).
