Much like tafode, I couldn't get it to work on PC or Mac. Just wouldn't recognize my camera on either laptop.
His suggestion for using the phone was good though. At least I was able to get it started...but tried several times and lost pretty much instantly. Pack of little dinos moved maybe a few pixels when I was leaning as far as possible...and all got crushed in one go. (probably the screen size didn't help me much)
Really ambitious trying motion controls though. I don't think I could do it :)
