A game machine determines the reference timing included in a predetermined time range and the crossing direction position corresponding to the reference timing based on the sequence data (30). And, the game machine causes an instruction path (R) extending from one end side (UP) in depth direction (TD) toward the other end side (DP) while passing through each crossing direction position corresponding to each reference timing at a position on the time axis corresponding to each reference timing and the reference line (TL), to be displayed on the game screen, and decreases a distance between each position and the reference line (TL) with a decrease in a time difference between the reference timing and the current time.
