It is indeed a work in progress, but there is more to do than just walk around. I believe the NPC "Celeste" on the 'demo' server will explain how to get sysop key, and you can then edit the map.
There might be a post here somewhere on it as well, basically just enter "/key" and you should get a sysop key (only works on the 'demo' server, not Queville or Anarchy servers).
The next update will give you "health" stats and hopefully some fishing, cooking, and eating. We are making progress. :)
