This is great! You owe it to yourself to add a bit more :) I bet you'd get a great result in terms of interest. I like the list of additions in the comment below. The "Buy All" being chief amongst them, I was cursing you while flogging 90 Wood to get funds for the new puppy :)
I can see how the NPC characters be fleshed out with a little narrative etc. (The puppy woman was pretty quiet after I gave her all that gold...)
Apart from anything else, I did find myself sinking a solid 45 mins into it - didn't want to put it down until the puppy and some sheep were mine to pet!
