Abstract: A timing game device includes a virtual-space image display unit 13, a movement-line display unit 14, and an object display unit 15. The virtual-space image display unit 13 generates a virtual space image, based on VR image data in which a hit area is set in a virtual space having a range wider than a view field of the HMD 200 and displays the virtual space image on a HMD 200.
