Memory Lanes is a puzzle game where the player leads the character through mazes with walls and non-player characters (NPCs) while manipulating the state of the world around them to reach the goal. Player uses W,A,S,D keys to navigate the character through the maze. Player uses O to save a certain state of the environment, memorizing the states of all the doors at that point. Player uses P to reload the most recently saved state, setting all doors to their last saved state. Player can “trap” NPCs to keep them standing on switches that open/close doors for prolonged periods of time
