Great concept and artstyle. I think the gear crafting and equiping needs more work.
You need to click to much to craft multiple gear. If I want 2 craft 2 pickaxes I shouldnt have to click the pickaxe again before I craft a second one, just leave the selection. I also need an overview of what my miners have equiped because the visuals are too confusing, I need like a table of all miners with their equipment.
