This is a single player defense game for interstellar strategy. We have established 36 birth points. Players can freely switch birth points to control the size of the enemy. The game has three coordinates. The first one is to display our coordinate position. The second one is the coordinate input point G where the perspective needs to go. The third one is the coordinate point G that our unit needs to go to after inputting. Left click on the object image to move it out of our unit. Clicking aim at our unit will aim at the enemy. Clicking to move our units will move towards the enemy in sequence. We will set the moon as the base. Our fleet can conquer the universe and find legendary warships. Our journey is the sea of stars.
