Crafting Game Prototype

This is a very early prototype I have been developing in my spare time for a crafting gameplay idea. The (ambitious) goal is to make the crafting part of a MMO, RPG or survival interesting enough to be played as a stand alone, without taking part in any of the fighting or world exploration, just essentially do the job of an NPC (here a blacksmith). If I can achieve that then I could draft a mobile/online RPG where players can be truely be dedicated to one job. Either fighter, blacksmith, tailor or other professions. They could then trade the fruit of their labour with other players. I think it would be an interesting experience, closer to mmos depicted in animes like Sword Art Online. Thank you for trying this prototype, don't hesitate to leave feedback or ideas in the comments !
