I have played many space shooting games, but this was so awesome I had to check it out. I think the main reason it's so awesome is because of how simple it is. You are on this interesting area and background where you blow up enemies over and over. I also like how you have so many lives. Some of the sounds are goofy, but fine. I'm speaking of when the boss fires at you.
The controls are really easy to understand. You get an interesting variety of enemies that are coming after you. I don't even know if you can kill those metal UFOs. I swear I didn't get more than 5 points at once from those coins. I thought they were energy blasts you were supposed to avoid at first!
