In Galaxy Force players take control of a spaceship in an attempt to save their galaxy from a dark force. Players are only given one life but their ship in equipped with shields. Four planets exist which represent scenes -- each split into two levels -- that can be played in any order. The first level takes place on the surface of the planet and the second one takes place inside the core of the planet. While on the surface players can move in all directions while shooting enemies. Inside the planet the game requires precise flying as users must maneuver through small tunnels and avoid hitting the walls.
