I had a few more things I wanted to say, but I didn't come up with them until I read some of the comments...
+Third person
+Decor upgrades [More decor = more impress customers, decor could be windows, or a plant, maybe a bench or a sign, etc]
+A skill which allows you to carry multiple things at once [Heaving lifting]
+More weapons like war axe, throwing stars, bows [using a bending machine purchased in the shop upgrades]
+To do list
+Smaller ingots
+Industrial furnace [Has a more flat surface and heats things up faster, purchasable in shop upgrades and adds decor]
+Ingot price adjustment
+The ability to make siege weapons
