Gather iron ore from the mine.
Melt it in the cauldron and take the molten iron to the blacksmith.
Quickly deliver the swords made by the blacksmith to the soldiers.
They need you to win the war.
While the basic concept of a dwarf helping to supply an army of giants with weaponry is a neat one, the game as it currently stands has no features beyond the basics beyond the first battle. Win the fight if you d/l this app, then move onto something else.
Hopefully the designers will add additional features into an update, since they do have a very nice base concept.
