First thing first, I love the game! I have played it for many days and I have enjoyed every moment. Yet, there were few things that I'd like to suggest for now. I'm sure there has been loads of suggestions already, but these are the ones that I'd like to change.
1. It would be nice if you could go to bed whenever you want so you don't have to wait the whole night.
2. Also, as the night is so dark, it would be nice if you could craft or buy some lights on your property. The small lantern doesn't really do all that much in some places. It does well in your shop, but not so well at outdoors or even in the mines.
3. As you start making higher tier weapons, it becomes meaningless to make cheaper weapons anymore. You wait customers to buy the best tier weapons you can make but they just want lower tier stuff. While it's fun to make them for the first three hours, it can get boring pretty easily and this is critical to keep players interested. I don't really have any suggestions for this, but for now, I just stand behind the counter day after day waiting to make a profitable sale. Maybe you could decide what tier to sell or something. I noticed that if I left my Mithril weapons on the counter and the customer wanted Adelite weapon, they took the Mithril one if it was the same type of weapon they wanted. This was a small help but as you go higher it's still quite rare.
4. Make the horse so you could ride it without the cart and put small items into a saddle bags. Bigger items like logs would go to that cart. Saddle bags could work like small inventories so the items wouldn't fly around.
5. The player could also have a small inventory for a couple items so you don't have to throw stuff around 1 piece at a time.
6. You could make some customers to pre-order some stuff for the next day so you can make them ready when they come to get them. These orders could be more profitable than normal orders and include more items customers wants to buy. Another way to do this could be a bulletin board where the player can go check if any customer wants to order something special.
That's all for now, I really hope this game will continue to develop and I'm definitely looking for the future updates!
