Space Dog - is to control a space dog to roam space and avoid meteorites. If the space dog encounters a meteorite attack and fails to avoid it, the game will be over. Each time the space dog avoids a meteorite or knocks it away with his lightsaber, the player will receive a point. Space Dog specially adds a lightsaber and a space helmet as props, and its health can be increased once, making it easier for players to pass levels.
