Confused – Mystery of Unicorn Castle HD Review

I can't rate this as I can't get it to download onto my iPhone. The requirements for this game indicate that it is iPad compatible but it is for the iPhone OS 3.2 or later. I can't get the app to download onto my iPhone and the app only shows up on this site under iPad Apps. Please let me know how to get this to download onto my iPhone. Thank you.
