Has anyone tried Skybound ($2.99)? It looks like a very polished and unique game. There's a video on their site. You basically draw clouds that a ball (or something) bounces off as it rises higher and higher. The clouds disappear pretty fast, and you can angle them to direct the ball to objects like powerups, coins, etc., some of which they bounce off of and interact with. The game has a very nice painterly look. Anyone pick it up?
