I successfully crafted a D-Tier Longsword!!
I think you have some great ideas on your hands; the drawing is fun and I like the vibe of just walking around and buying/selling things. It took me a while to figure out how to craft a sword though; I knew what materials to add but didn't realize I had to put them in order them properly. It would also help if there was a button to quickly access recipes in the Manual so I don't have to click through everything.
I would love to see this expanded and would definitely buy this as a fully-realized game!
