1. A computer-readable storage medium having a game program stored therein, the game program causing a computer of a game apparatus, which includes a display screen for displaying a game image and a touch panel provided on the display screen, to implement a method comprising:

  • a game image display control step for allowing a game image containing one or more game characters to be displayed on the display screen;

    a coordinate detection step for detecting a coordinate value at predetermined time intervals, the coordinate value indicating a position on the touch panel where a player'"'"'s input is provided;

    a shape identification step for identifying a graphical shape of an input trajectory represented by a coordinate value group detected by the coordinate detection step;

    a size calculation step for calculating a size of the graphical shape of the input trajectory represented by the coordinate value group detected by the coordinate detection step;

    a basic condition determination step for determining a basic condition for changing a characteristic parameter, which indicates a characteristic of a game character, based on the graphical shape identified by the shape identification step;

    an effectiveness determination step for determining an effectiveness of the basic condition for the game character based on the size calculated by the size calculating step; and

    a characteristic parameter change step for changing the characteristic parameter of the game character based on the basic condition determined by the condition determination step and the effectiveness determined by the effectiveness determination step.
