Oh, so it was much simpler than I though, tanks for explain.
Well, you can definitely add those suggested mechanics, with multiplayer just send messages from peer to the host and vice versa and you can easily do it. It doesn't matter if no on knows you, you can do it for getting use to create multiplayer games, increase your portfolio and show that you can build multiplayer games and finally invest for the future. No one might know you now, but the game will still be there. Even after one year from its release, people can discover and play it. Also you might be willing to add it to game portals, giving you an additional route for getting income from your game ;-)
