The two times I've attemted to finish, everthing has been going fine, and then I accidentally destroy my castle by clicking on the X button. I keep thinking it's a "clear dialog" button. Perhaps a more descriptive button, like with a burning building on it, would help. Or at least a "are you sure you want to destroy that..." dialog.
I persisted, and managed to complete the "A New beginning" map without destroying my castle. I didn't record the time, but it wasn't great. I had the ratio of workers assigned to breadmaking, compared to those assigned to fishing, all wrong to begin with.
Oh, and I forgot to say earlier: Well done so far. I'm impressed with how well it all works. I'm sure it's taken a lot of effort to get it this far.
Something that I think could be improved however is the handling of workers. Having to hold W or C and right-clicking on a building is a bit cumbersome. I found that I was using W a lot more often than C, so perhaps if you made right-clicking automatically perform a W-right-click, and then use the C-right-click or Shift-/Ctrl-right-click for carrying.
I also found the small white-text that ran along the bottom to bet a bit too small for me to read. I had to move in closer to the monior to be able to read it.
There were a couple of other small things that I've now forgotten, but I'll note them down when I play the second map.
Again, well done!
[edit 2]I keep getting crashes at random places in the second map.
