Just a quick thing, I bought this on Steam and LOVE it! I just wanted to say that it seems as if buying energy from certain vendors doesn't give the energy it says it does. For instance, in the city, buying beer from the beer lady and pumpkins from the pumpkin lady (5 gold for 10 energy), as well as the mushroom lady in the Underhill, don't actually give you the 10 energy. (If it did, my meter didn't go up after the purchase)
Still, this game is fun! I can't think of any other issues I came across.
