Developed by Treasure, Mischief Makers stars a robotic cleaning maid named Marina on a mission to rescue her kidnapped creator from the clutches of an evil emperor. As with most evil folk, the emperor isn't about to just hand over the aging scientist, and has amassed an army to stop Marina at all costs. To reach the emperor and rescue her creator, Marina must make her way through five different worlds with 12 stages each. While some levels focus on straightforward action, others present the player with puzzle elements that must be overcome in order to make it to the goal. Released in Japan under the name Yuke Yuke! Trouble Makers by Enix.
