You progress through the game by upgrading room controllers. The higher the room controller level the more structures types you are able to build and higher up the tech tree you can go.
At the moment my room level is 5, and my place is finally self-sustaining.
But I know before long I’ll have access to more complicated structures, global market trade, and other rooms to try and spread out too.
So I’ve decided to run a private server, with a version 2 of my code.
If I treat this first week as getting to grips with the game and tutorial, now the real fun begins.
