Your mission in this good arcade / console style game is to destroy all enemy ships. Use the ARROW KEYS to control your ship. Press the SPACEBAR to shoot. Press "B" KEY to switch shield color or shot polarity. Enemy bullets in same color as your shield color won´t reduce your ship´s energy. Changing polarity of your shots to the opposite of the enemy's color increases the effectiveness of your shot. Some enemies will drop Eclipse Tokens or power ups. Collect these to increase your score or enhance your ship for a short while. Good luck!
