On the title screen, click play and it will take you to a hangar, where you select your plane, weapons, and the boss you fight. When you start a fight, you just need to shoot the boss until it has no health left. And avoid its attacks. You can move your plane using either the arrow keys, WASD, or ZQSD (if you have that kind of keyboard) You shoot your main weapon by pointing and clicking with the mouse, or you can enable/disable auto-fire mode by pressing E You shoot your special weapon by pressing space when it is ready. You will hear a sparkle noise when it's ready. There is also a sign in the bottom left, just above your health, that will tell you when it's ready. There is information about what all of the planes, main weapons, and special weapons do. Just click "Info" on the title screen. You unlock more bosses to fight, more weapons to use, and more planes to fly. These are all unlocked by beating bosses for the first time. If you want a bigger challenge, you can try to get the gold portrait of the bosses. To do this, just beat them without taking ANY damage. It may be tough. Turbo mode makes the game glitch, like you will die in one hit or something. So don't use turbo mode.
