To provide a game device that allows a user to relatively easily judge a time at which a length of a gauge becomes a length with which desired processing is executed. A first gauge control unit (72) controls the gauge to expand or contract according to continued of pressing of an operation member. A second gauge control unit (74) controls the gauge to expand or contract according to the continued pressing of the operation member, and in particular, switches a change to be given to the gauge between expansion and contraction based on a numerical value output from a controller according to a pressing force with respect to the operation member. A gauge control switching unit (70) causes the second gauge control unit (74) to start gauge control when a length of the gauge is set to a predetermined status by the first gauge control unit (72). A game processing execution unit (80) executes game processing based on the length of the gauge when release of the pressing of the operation member is detected.
