MOBILE COMPATIBLE! At the start, there is one big blue-ish circle. Click/tap and hold it to change it's color. Click/tap it and don't hold to make 10 small circles of that color. Then click/tap those smaller circles to create 2 more. Every time a small circle is created, it has a 5% chance of mutating to another color. Btw once there are 300 (299) small circles, they will no longer make new ones. I can't do anything about that.
Nothing.
