OK so this title looks weird to you probably right? anyway. Agar.IO is a science based game so you will start of with a little blob and you can name its what you want :). If you type in certain names like Mars you will turn into mars you can also download music but i wouldn’t if I were you because there are lots of dodgy websites out there you know. Anyway this is just a game you don’t have to download it just search Agar.io and then start playing yay!
