This is basically the same as regular agar.io, use the mouse to move around your ball, and try to eat as much as possible. Unfortunately, you can not split your ball. There are still a few things that i'm trying to figure out, if you look at the code and know how to fix the problem with touching larger or smaller balls, leave a message in the comments.
I got the original idea for this project from Hackingtons Code School for Kids's How to Make Agar.io on Scratch Youtube Video.
