< Feedback de Agar.io Core Mutation by zagar
One of the better (and still working) extensions I use is called 'Agar Tool', which is still used by many people.
It includes a map, a chat area, shortcut keys to to split commands and things like showing your split area and if you can eat other players or not, by outlining them with blue and stuff.
And no, this isn't an ad or smh, I literally use this almost every time I ply Agar.io. just try it. :)
can someone make an extension with attack range for gota.io?
it is hard finding a good extension
