Coding question: Add split and shoot on agar.io game

Hello @shiffman. I tried to improve myself with coding with the game of agar.io from your source code, i added some functions like a map limit, collision with borders, random blobs to eat when the number of current blobs is low, etc. But i am hardstuck on trying to make it split, merge or shoot blobs. Could you try to make it if it interests you and if other people's stuck and interested on that?

Thank you in advance.
