Very pretty. I thought a bunch of chicken noises would get annoying, but surprisingly no. The theme song is pretty fun too. I would have like it if the "Incubate" and "Orders" tab were a little closer to the chickens tab in the order. I wanted those to the most, and they seemed to be the most clicks away in either direction (especially with the empty achievements pane).
Very engaging, I played it until I maxed out all but cluck Norris (who just stopped letting me by upgrades somewhere in the mid-500s. The button was green but unresponsive)
