A Mysterious Thief was canceled before its release. In the game, players control a thief who must rob as many houses as possible without being spotted by residents or hit by enemies. Using a platform-based system, players need to reach the purple line to move up or down floors. But be careful—many enemies will appear to hinder your progress. Only a prototype version is available for play, as A Mysterious Thief was canceled prior to launch. The objective is to grab items that appear in the windows, but it’s not easy, as you’ll need to dodge dogs and apartment residents along the way.
