I really love fiction of the game! I'm amazed how some layer of fiction make game interesting. Music is really fine.
This is kind of game when you start playing it's addictive :D
I like idea of mechanic that you can add some extra wood construction to better fill-up empty space, that's really helpful but at cost of wasting space where ppl could live, just great design.
Congratulations on your submission! *clap*
