Rhythm game program and game system

A non-transitory computer readable medium storing a rhythm game program for causing a server device connected to a game terminal device configured to execute a rhythm game by playing a music and displaying a trigger object on a display by a communication network to control a progress of the rhythm game, the program causing the server device to execute functions comprising:

• evaluating an operation input of an operation unit of the game terminal device, based on a timing of the operation input for the trigger object and an operation timing associated with data used for playing the music;
• moving at least one of the trigger object and an operation position to decrease a distance between the trigger object and the operation position decreases, based on the operation timing corresponding to the trigger object;
• causing an auxiliary character to appear when an appearance condition is satisfied;
• and
• causing the auxiliary character to execute an auxiliary operation to assist a user in a progress of a game.

A game system comprising:

• a game terminal device comprising
• a display;
• an operation unit configured to receive an operation input;
• a processor configured to play a music and further configured to display a game image including an image of a game space including a trigger object on the display;
• and
• a server device which is connected to the game terminal device by a communication network,
• wherein the game system is configured to evaluate the operation input, based on a timing of the operation input for the trigger object and an operation timing associated with data used for playing the music, and
• further configured to move at least one of the trigger object and an operation position such that a distance between the trigger object and the operation position decreases, based on the operation timing corresponding to the trigger object, and
• wherein the game system is further configured to cause an auxiliary character to appear in the game space when an appearance condition is satisfied, and to cause the auxiliary character to execute an auxiliary operation to assist a user in a progress of a game.
