Originally released in 1986, this title is a rolling action game. Players control the "Survival Ball"—a sphere governed by unique inertia—aiming to clear all 12 stages. The courses are filled with monsters and deadly traps, but you must also manage energy depletion from movement and damage. Packed with puzzles like hidden passages, it is a deep, highly replayable title that lets you enjoy thrilling, fast-paced action.
