Hey! Thanks for your feedback. And it would be nice if you could bring more people to the game but I'm a bit worried, because I already had 2 people who promised me to help with advertising but they just disappeared...
And nails:
Get at least 2 iron ore (grey), add them to the blacksmith
set the mold for smelting like in the recipe and start smelting. I would improve UI and this mechanic in the future updates.
