Use the arrow keys or a and d to move space ship. To start, press the Start button and if you want to end the game early, just press the Quit button. You get 3 lives to score as many points as possible. Each alien type is worth different points depending on their difficulty. Beware, hitting barriers minuses points. To shoot lasers, press the space bar or e and do not press again until the laser has disappeared. Enjoy! :)
