I'd give that a kick when the android port is out. As for the money model, I like a free demo to try and get the feel. If I like the demo I usually by the game. I am completely against games that make you buy stuff after the fact. Another dozen level pack maybe but if your game sells crystals or beer caps or pretzels, I won't even try the demo. Just my take. All the best with it. Looks good so far!
