Abstract: In this program, a regulation command for controlling the movement of a first character is recognized by a control unit. After the regulation command for the first character is recognized by the control unit, a movement command for operating a second character is recognized by the control unit. Then, the state that the second character is moving based on the movement command is displayed on an image displaying unit using image data. The first character with movement controlled based on the regulation command is displayed on the image displaying unit using image data. And, if the receiving of commands related to movements for the first character and the second character is terminated by the control unit, a process for changing the ability data of the first character is executed by the control unit.
