Interesting game so far, I love the art style and the automation gameplay seems fun, but it needs some improvements.
There is an issue where coins or other items would get deposited into different things I didn't want to upgrade because I walked too close to it or I would pick up items I didn't mean to. Also trying to put a sword, shield and armor on the stand for the fighters is difficult because you can only put 9 items on there, which means you would need 3 of each, but you always pick up as many as you can carry whenever you walk pass (maybe you could put it some sort of button that would pick up the items or something).
Unfortunately, the game glitched out and broke on me, I was crafting metal swords and the boss died. This left my character going (needs metal) over and over again and unable to move. Even tried reloading, but I can't move.
I see a whole lot of potential here and I'm really looking forward to seeing where this goes. I really love the art style and the music is good too! Keep at it and I really hope things go excellent with the game going up on Steam!
