A couple note on the UI: At first I think I was clicking too much and some of my guns disappeared! Later on, I had so many guns it was hard to track which one was the new forged gun. Could be nice to just add Mk. I, II, III... and so forth to show how many times the gun has been forged? Not sure how that would work if you forged a Mk. I with a Mk. IV... so maybe that's not gonna work either. Other technical notes: the camera movement was a little disorienting. It seemed to track to my mouse position if I was centered in the battlefield. When I moved to the outer perimeter, my camera got panned way out and was hard to see where enemies were located.
Overall, it was a fun survivor game with a unique meta mechanism. The pixel art for the guns was also really cool! Great job
