A game device 1 that executes a game program stored in a storage medium of the present invention detects and stores coordinates on a game image corresponding to an input while the input by the player is detected. Then, based on an input locus having a predetermined shape shown by the stored coordinates, a direction shown by the input locus is calculated. When the direction is calculated, the game device determines whether or not a coordinate of a starting point is included in a predetermined range 35 that is based on coordinates showing a position in which the player object 32 is displayed in the game image. When it is determined that the coordinate of the starting point is included in the predetermined range 35, the player object 32 performs a moving action in the calculated direction. When it is determined that the coordinate of the starting point is not included in the predetermined range 35, the player object 32 performs a kicking action in the calculated direction.
