The life of bacterias is full of challenges too. You can make sure of that playing agar.io. Your goal is to grow a tiny amoeba into a huge and glutinous virus swallowing all other bacterias on its way. For that you need to collect colorful dots and eat them. Every piece will increase your size until you become big enough to stop hiding and walk out to fight other organisms. The more you eat the larger you get. But there can always be a virus bigger than you, so don’t lose vigilance even if you barely fit into the screen!
