In the game Bubble Space you will go to the micro universe inhabited by various races of creatures. Some of them are quite aggressive and constantly attack others. You will need to protect one of the planets from their invasion. On your ship, you will patrol the space around your planet. As soon as you see the enemy ships, attack them. Firing from your ship's guns you will have to shoot down all enemy aircraft. For this you will earn points. On them, you can later upgrade your ship and significantly enhance its weapons.
