Entertaining, but lacking audio.

I liked the gameplay and the concept. My main criticism is the audio. There is none. Adding some audio to the game would give it a better feel. I also didn't like the color scheme. A black background instead of light-blue and white lines instead of red would appeal much more to me. But that's just my personal opinion. The game also lagged a bit at times. Polishing that up would be a major improvement.

Although I do have some criticisms, there were also some things I like about this game. I like the concept of fighting off two sides of ships instead of one. That makes the game more of a challenge. I also liked the fact that the enemy ships were identifiable not only by shape, but by color. It gave the game more personality.

Overall, it was an entertaining game. It just needs some polishing.

Good, but with some problems

It is like space invaders, but it has more detals, because it fires at you from behind. The game aso won't let me submit my score. It would also be cool if yo add your own backround music, that changes depending on what your doing or if you have a power-up. Either that or you have standard backround music, that lasts through the time you are playing. Other then that, it's a great game.

Hello silence my old friend!

Put some music there, should do the trick.
