Rating: 4.8/5
Take control of a spaceship and shoot down projectiles fired from a UFO before they destroy all the three Earths. When you begin, you will have a wall protecting the Earths and each time you get 10000 points the wall will be rebuilt. The UFO will start shooting projectiles which will get faster and smaller as you progress, making them harder to hit.
