A game apparatus includes a game machine and a game cartridge. On a case of the game machine, operation buttons are provided. On the LCD, game images of a player object and non-player objects in a game space are displayed. For example, a player, by holding the case with both hands and operating the operation buttons, controls a holding action of a left hand and a right hand of the player object. When the player instructs the player object to perform the holding action, if the non-player object exists at a position where the hand of the player object exists, the non-player object is held. In a case that the player object holds the non-player object with one hand, the player object rotates, and by changing the non-player object to be held, the player object can move within the game space. Furthermore, if releasing the hand from it during the rotation, the player object jumps out.
