A past operation history can be presented in comparison to the current operation state to a player. In a game device (301), according to the movement instruction input received by an input reception unit (302), a first movement unit (303) moves a first object in a virtual space. An input history storage unit (304) stores the movement instruction input as input history information. A second movement unit (305) moves a second object in the virtual space according to the input history information previously stored. A judgment unit (306) judges whether the first object and the second object are superimposed on each other in the virtual space. When it is judged that they are not superimposed, a display unit (307) displays the second object. When it is judged that they are superimposed, display of the second object is terminated.
