This is one more clone of Space Invaders. Maximum simple. Black and white.
You play as cosmonaut, and you are from space forces. He can shoot from blaster. Near you, there is a group of sputniks. From one hand, you defend them, from another hand, you can use them as shields against intruders atacks.
