use left and right arrow keys to move, spacebar to shoot a plasma beam, A to shoot an energy beam (60s recharge), S to shoot an energy bolt, D to shoot a plasma burst. 1. sometimes if you press one, ships will not spawn properly or the background will sho the main menu or the GAME OVER page. (glitch common if pressing 1 after death) just press one again. 2. sometimes the first ships disappear for no reason. just press one again. 3. Gameover screen apears and it won't go to the menu: to solve this click the green flag or press three. if you find glitches please tell me.
