Few more ideas:
-Some achievements, like X Gold, X items sold/created, X materials mined, X items purchased/sold on market
-Few more items in the market, and an option, to set how many you will buy (or maybe not needed)
I would (personally) like to see an adjustment in the market, like, the apple will rot if you keep it too long, or, the wine becomes a little more valuable, because you keep it longer, and it ages a bit.
But, else, it's good. 4/5
