Amazon.com’s free app of the day is “Micronytes“! Micronytes is a game in which you go into a body (on a microscopic level, of course) and go around killing germs. While it’s not entirely accurate- most bacteria don’t have teeth, it’s an entertaining little game for your Android phone. Head over to Amazon for a download. It’s free today; you’d have to be a fool not to take advantage of that deal!
