IPC: A63F13/218
Filed: 2006-01-19
Abstract: A game device in which a player can relatively easily determine timing at which a gauge has a length suitable for performing desired processing. A first gauge control section (72) elongates or contracts a gauge as the first gauge control section continues to press an operating member. A second gauge control section (74) elongates the gauge as it continues to press against the operating member, and particularly, the second gauge control section (74) switches a variation imparted to the gauge between elongation and contraction based on a numerical value outputted from a controller depending on a pressing force applied to the operating member. When the length of the gauge is brought into a specified state by the first gauge control section (72), a gauge control switching section (70) starts gauge control by the second gauge control section (74). When release of pressing against the operating member is detected, a game processing section (80) performs game processing based on the length of the gauge.
