A computer program for a game system is constituted to allow a computer incorporated into a game system, which comprises an input device having at least one operating section, a display device that displays and outputs a game screen, and a sequence data storage device that stores sequence data having described therein an operation timing of the operating section during the game, to serve as:

• an operation guiding device that determines an operation timing of the operating section, which timing is included within a predetermined period range from a current time on the game to the future, based upon the sequence data, displays an operation instructing indicator corresponding to the determined respective operation timings and an operation reference indicator corresponding to the current time in temporal order along a predetermined path on the game, and produces a relative displacement, which is along the predetermined path and is according to the progression of the time on the game, between the operation reference indicator and the operation instructing indicator in order that the operation instructing indicator agrees with the operation reference indicator at the operation timing that should be indicated by the operation instructing indicator, by which the operation on the operating section is guided to a player, and wherein
• the operation guiding device to serve further as a path changing device that changes at least either one of a starting position and a reaching position of the predetermined path.
