Instructions are pretty simple once you play the game. Just press the flag and it's pretty self-explanatory.
UPDATES- 8/16/2015 Fixed the glitch where it takes away money when trying to buy a second blacksmith. (you can only have one) It took me about a month to finish this game. I'm really proud of this and I hope you enjoy it! WOW! I cannot believe how much feedback I'm getting from this game. Thank you everyone! P.S. There wasn't really that much money circulating around during the middle ages (people would barter), but I made the currency coins just make it simpler/easier to understand
