It can be done, but requires quite a lot of fight, as you need to make sure all the players are 100% in sync (what species players selected, then the random reatures of the game as well), more over you need to make those connections before the game started and then route the traffic.
In fact we need part of the game to hosted by one of the players (as a server) or using the central server.
But it is totally doable, just heavy and might (not sure how much is left currently) require more memory than the base 64kb.
To error is human, to forgive is not our policy.
