I liked the gameplay, nice to see something thats not just a cookie clicker.
I also learnt a valuable lesson:
if you have an endless supply of donkeys then its cheaper to work them to death than to feed them
Yeah, that's one of the references to the dark side of capitalism—you could even set up a slave system there, because you can catch these donkeys when they run away and bring them back to the fields =) Well, if you're quick enough.
