Hi there, thanks for playing. Unfortunately when you've finished building a room, it is fixed. This is for a number of reasons and it's quite hard to fix, but more than you have asked for it, so I guess I'll have to fix it some day.
Research, yes it's all I got, but they can be added by anyone in a file and it's very simple. Of course more should be added, I just haven't gotten arround to it.
Right now the world map serves little purpose and the engine only supports one city at a time. This will be fixed in the future.
No battles or diplomacy yet, but on its way.
