Fun idea!! I really liked the system of placing gold bounties on goblins, and having to entice the spoiled heroes to go do it. I didn't feel clear on what the buildings were really doing, but I did buy them all anyway :D
I was going to say basically the same thing jerbaloot said, just having the heroes physically appear in the village, I think that'd make it much more fun as a kind of 'tycoon' game. Awesome concept though! I'd love to see a post-jam version of this!
