A game system includes: a direction mark storage section which stores image data of a direction mark that specifies a player's maneuver; a display controller which controls display of a plurality of display objects including the direction mark; a timing fetch section which fetches a maneuver timing; and an evaluation section which evaluates player's performance, based on a result of comparison between the fetched maneuver timing and a reference timing. The display controller displays the direction mark to specify a combination of a series of consecutive maneuvers by a single mark. When the player has input a series of consecutive maneuvers in accordance with a direction of the direction mark, the evaluation section compares the timing of the series of consecutive maneuvers with a reference timing, to evaluate the performance of the player.
