This game is much better than the first, a few suggestions to improve on though.
1. Items that increase gold when an item is sold be proportional to the item sold and not a set amount by level.
2. On the city screen instead of donating a specific number of item, make it so you can donate however many you want, same with gold.
3. Being able to see your resources in the city screen, so you know if you need to switch out workers.
4. Items that can reduce craft time, or just increasing craft time with each upgrade of workspace, like iron anvil to steel anvil cuts production time down by x%.
