Great game honestly!
I think the game has a big potential! Nice graphics, smooth gameplay and concept. The system of crafting weapons and customers coming to us is nice. I liked the models too. I also liked gathering resources to make our weapons and running our store. Upgrading our weapon creating possibilities (discovering weapons) was nice.
Here are some of things that brought my attention:
I think the game would be better with mechanic of inventory, which you could always open and throw out some useless materials (or just worse tiers of ore).
There is a way to abuse game mechanics - you can just create previously made part on an anvil without any resources taken, but those parts are just worth 0 coins - 3:50. Maybe you could prevent it by resetting the part every time after creating it on the anvil (so the players have to pick the part, that they want to create).
Map seems dead. There is nothing in the houses, the world is empty except our shop. I really liked the map overall, little pond and houses, trees, nice colors and textures, it all feels clean, but still you see empty room while entering to one of the buildings. Also there is no easter eggs and I think this map could have some, because it's big and has a lot empty spaces to place some.
There could be like a book (just source of information) telling you what parts you need for different kinds of weapons, because you need another parts in hammers than in swords for examples (which was hard for me to find out - 14:45).
Some system of upgrading our tools or equipment would be great. Better furnace or axe for example (by buying it or by adding materials like iron, or both money and materials). Also more ores would make the game more interesting (maybe tin, diamonds or something). Maybe buying a backpack to make our inventory bigger. Maybe buying another slot for orders (so you could make 2 weapons at the same time). Customizing our shop maybe.
Animations could be better (mining and chopping), since they feel kind of stiff, just not smooth.
But the game is good for me overall! Strong 4/5!
