Sorry, I'll be honest, but I got completely lost. I had no idea what to click, what was going on, and what was the goal. I can imagine that this is an interesting game, but right now I did not understand it at all. I put a farmer on the barren. It didn't produce food, so I pressed the red button. Then it got killed (?) and made something. There were options for things to build popping up on the left, but I couldn't do anything with that. I also gut some staff, again no idea what to do with it. I put some farmer into the castle, it ended up being stuck there with some yellow line thingy when I tried to move it. No idea what that was for. (Attacking maybe? But there was nothing to attack...)
On top of that the texts were very small and hard to read.
So, I see that this is ambitious, but right now it needs a good tutorial, I think!
