Seem like a very nice game! I appriciated the tutorial, and ramping up things slowly..
However, maybe I'm dumb, but I couldn't figure out how to smelt iron lol.. I crafted the pickaxe and smelter, but when I clicked on the iron deposit it still red. tried to drag the pickaxe to the map, and place the furance, but it wouldn't let me
Could be cool to continue after I understand those things
