This game is very interesting, very addictive, and rather intense. (In a good way) however, my addiction to it was not for very long because, like most games of this genre, it manages to get overly redundant after a few days. And, there is so much they could very easily add with just a little imagination. Like, I dunno, other planets like mars that have different invaders or something. Or like add power ups. (Although if there is some things such as these added, there should still be the classic mode as there is now) But this game is good, and I recommend it to anyone whom is reading this. (But keep in mind that doesn’t mean I recommend it to everyone, only the readers of this review. I know it’s a little weird, but I have my ways) 7.5/10 might re-download, WILL re-download if it has a major update.
