Ok if you're having the same issue as me: after you download you have to click "llama villa" then click "Extract all" then you'll be able to play.
Now that I was able to: it was an enjoyable little game. Suggestions I have are a menu option? I didn't seem able to pause, save, or exit the game. I had to turn off my computer to exit. Also once I got to 6 llamas, I was making way more money and having to sheer them faster then I could actually build. I would say the more expensive the llama, the longer until sheer time, but worth more money. Maybe that will add more of a balance.
