shoot the enemies with the space key and fly around with the left/right/up/down keys. press m to shoot missiles. shoot the hearts to, well, we all know what that would do. you regain one missile after each level. WILL YOU MAKE IT TO LEVEL 5?
sometimes the enemies spawn on the control Pannel, so don't forget to look there! (If you do forget, your dead.) ammo is unlimited. I just thought it was cool to add it in there. SOUND IS RECOMENDED!
