I'm sorry, but I really couldn't get into this. I think the main problem was that it was just too simple. I don't like the idea of just moving these guys around over and over. It's amazing how you're able to make this fairly complicated. I will give you that. I just don't care for the gameplay.
I'm somewhat impressed at all the other games you made in this series. The music is alright. There's just nothing too distinct about it. The names are kind of funny. The space junk does kind of contrast well with their appearances.
