A game device has a playing unit, a receiving unit, and a changeover unit. The playing unit plays any piece of motion image data as play-target motion image data among plural pieces of motion image data. The receiving unit receives an instruction input of specifying a position. The plural pieces of motion image data include motion image data associated with a set of a time period (a changeover time period) in a playing time of the motion image data, a position (a changeover determination position), and any piece of motion image data (changeover motion image data). The changeover unit changes over the play-target motion image data to the changeover motion image data when (a) the changeover time period includes a time point when the instruction input was received, and when (b) the changeover determination position and the position specified through the instruction input both satisfy a predetermined proximity condition.
