The demo supports 1-9 players locally, the full game will also support online, with any mixture of players locally (could have 4 copies of the game, with 3, 2, 2, & 2 players each).
You start each day picking a contract to fulfil, that could be iron ore, coal, wood, and a few other options. And then spending any money you have buying upgrades for your forge.
You then spend the day fulfilling those contracts before starting the next day, where you choose if you want to go deeper (maybe instead of iron ore you now process it into powder) or wider by picking another raw resource to deliver.
You can work your way up to smithing swords and can gain powerful relics by surviving long enough!
Check it out and let me know what you think here (please wishlist if you like it, but I'm also very open to constructive criticism, it's early stages right now but I'm hoping to get some feedback that I can build on)
Thanks for taking the time and have an amazing weekend!
