The spaceship that you will control is called Spark. Its task is to protect the approaches to the planet, being in orbit all the time and protecting its section of the conditional border from invasion. And it will certainly take place right now. At first, relatively few enemy ships will appear, but then their number will gradually increase. They maneuver and shoot at the same time, trying to destroy your ship. But hitting a moving target isn't easy, so move around and shoot too to shoot down all the ships before they can cross the border in Spark.
