Hi, I am new to java programming, but I was wondering if there would be some (potentially easy) way to convert a game which is multiplayer on the same computer into a game which could be played between two computers? The game I have in mind is slime volleyball, which can be seen here:

How would I go about turning this into a network game? Thank you for any help or advice you can give me.
