Hi Inquisitor Dave, Yes it doesnt have right now building option - it is stated in the description what you can do with demo. It was released to spot any problems with first build. Good thing is that new release with game-play like building, resources and weather is getting closer to be release ready. Version market 0.1.0 will allow players to play with limited amount of buildings but without any limitations in terms of mechanics ready for 0.1.0 release.
