The Janus Problem is a first-person, single player puzzle game where players can reverse time. Set in a virtual testing environment, players must get to the exit of each room.
Players create time marks which, when recalled, cause objects to move back to their position at that time. Players also have the ability to place time locks on different objects which preclude them from reversing. Using these tools, players must orchestrate the movement of objects to solve each level.
