Awesome game, I usually don't like minimalistic games, but this is just so cool!
I would really like to see some more progress on this, my main suggestion would be a tutorial, since when I first played the game, I personally didn't understand the controls, I had to look at the description multiple times, and when I got to building, I didn't really understand why some things, like wheat fields, indicate that food will go up, and farms don't, aswell as the functionality of lumber mills.
Still, great game, I support the development process, and I hope it will be an even better game when it's finished!
PS: I don't think a final goal is needed, having an end goal just doesn't fit the vibe of calm, minimalistic gameplay. What I think would be great tho, is some longer gameplay, such as more Outpost upgrades. This does not mean stuffing the game with too much features tho.
