This amazing game is in fact an educational game, but it is so freaking fun you don't even realize *cough*yes you do*cough*. In the game you are a Playpus unicellular organism that must survive and be sent to another planet. To do this ,though,you must fight againts viruses, hunger, lack of energy, coldness and stomachs. The game is fun and you learn a lot with this. My hint: Give it a try.
