World of IO

A huge open crazy world where life goes around the army of spores. Every player has its own tiny organism and has to destroy the hostile one. Build the largest cell and upgrade your molecule. Control your cell and watch out your powerful opponents who can destroy you faster. This is kind of a retro game, but more funny.

Eat smaller spores avoiding being eaten by bigger circles to become the biggest one! Develop you spores to evolve to be medusa, run or crawl through the maze of dangerous angry enemies. Use joystick to navigate your micro organism and tap. Think over your strategy to control your pattern and defeat the other players around the world!
