This game has turned out to be more addicting than I ever imagined. In fact, some days I can't seem to put it down. Who knew that playing a game about germs and microbes could be so much fun? I surely didn't. But now, I'm infected by this game of germs and I can't get enough of it. There are 36 levels to play, with more coming in the near future. That means more levels to conquer and more challenges. This is exciting news for addicted players like myself. And if you like to compete against the scores of other players, then the Game Center is perfect for you as you can see how you rank against others.
