This is an awesome game and has interesting mechanics with the player ship shooting from it's side with 3 projectiles at once. I like the computer AI on how it tracks and fires at you, which makes this initially feel difficult to dodge. But with some time it becomes easier to out maneuver and dodge the enemies attacks. The gameplay is smooth from the top down view. Id' recommend to zoom in more on the map, and possibly make the projectiles larger. Add some more difficulty to the AI.
I also like the intro screen and music. Plus an Options menu! Awesome!
