The game was a fully 3D polygonal first-person shooter hybrid with a pronounced platform jumping component. Players piloted a frog-like mech that could jump and then double-jump or triple-jump high into the air, as the camera panned down to help players line up their landings. In addition to shooting, jumping on enemies was a primary means of attack.[24] This was the first true 3D platform-action game with free-roaming environments, but it was never ported to another platform nor released outside Japan, so it remains relatively unknown in the West.[25]
