Game apparatus and computer program used for the same

A computer readable storage medium storing a computer program being applied to a computer of a game apparatus comprising:

• a display device including a display surface thereof facing upward;
• a plurality of operation units, each of which is disposed around the display surface, and has at least one operation member configured to output a signal in reply to an operation by a player;
• and a storage device configured to store data in which operations to be performed in a game to each operation member of the plurality of operation units at a same time are described in such a way that each of the operations is correlated to time in a game the time being a moment when each operation should be operated, the computer program configured to indicate the operation to the player at the time of the operation described in the data by moving an operation indicator from an appearance position on the display surface toward an indication position set for each of the operation units, so that the operation indicator reaches the indication position at the time,
• wherein the computer program is constructed so as the computer to function as:
• an appearance position control device configured to control the single appearance position on the display surface so that the appearance position is variable;
• an indicator position calculation device configured to calculate a required moving speed of each operation indicator, based on a distance from the appearance position to each indication position and a time span between the time when the operation indicator appears at the appearance position and the time described in the data, so that the operation indicator reaches the indication position of each operation unit at the time described in the data, and determines a display position of the operation indicator based on the required moving speed as calculated;
• and
• an indicator display control device configured to display the operation indicator on the display surface based on the position of the operation indicator determined by the indicator position calculation device so that the operation indicator moves by following the required moving speed.
