There are three rounds in this game. You are the blue spaceship; use the keys a, d, s, and w to move, and press space to shoot. In the first round, either avoid or shoot the asteroids. Shooting one will increase your score, but if the blue spaceship hits one itself, without using the lasers, you lose health. In the second round, there will be spaceships that will follow you and explode when they touch you, which deals damage to you, but if you hit one with your laser, you get more points. The final round will be a boss round; the boss will follow you and shoot lasers at you. You have to shoot the boss until it explodes. Good Luck beating the game.
