Here's what I think you should add:
- Implement magic weapons and an altar to craft them on into the game.
- Put a rod tab and a crystal tab in the order list to use them for these. (The rod would act as a grip and the crystal would act as a ingot, the crystal tab would have a large variety like the ingot tab)
- Be able to put crafted regular weapons onto the altar and slot crystals into them to make them better and sell for more.
- Add a variation of every weapon that has a hole in it for a crystal to be slotted into them (Except for the especially small weaopns that would be unable to fit them like the short blade
Add random encounters, for example a bandit stealing a weapon or money and also add a combat mechanic so you can chase after them and get what they stole.
Finally, I think you could add a questline to the game so that you always have something to aim for. E.g.
Gaining - gold, completing - requests, making - weapons
Thanks for taking the time to read this and a much bigger thanks if you would even consider adding this to the game.
