Hopper Copper is a single-player action game in which players control a character bouncing on a Space Hopper to navigate through a town and catch criminals. In this game, the player takes on the role of a policeman in Grove Town, where four dangerous criminals are causing trouble, and vehicles have been hidden by the criminals, leaving only the Space Hopper as the means of movement. It stands out with its side-scrolling view, map-based street navigation, and the unique mechanic of bouncing on criminals to apprehend them, all within a time limit, adding a layer of urgency and strategy.
