Micro World Evolution - To live means To struggle is a nice game about preventing a little bacterium from being eaten. One day a little cute bacterium decided to explore the micro-world full of mysteries. You need to avoid bacteria which are bigger than you or you'll be eaten by them. The bigger organisms eat the smaller ones – this rule of survival also acts in the micro-world. You should catch and eat bacteria which are smaller than you to become bigger, but escape from bigger bacteria or they'll eat you.
