I have collected every gurt scale but at the end when I had 22/20 nothing happened. Disapoiting. The camera is hard to control and full scren mode doesn't work. Also I can just run.fall through some objects. I had fun listening to the voices and the story. Just got to love how the cannon are saying : "Stay on target" "Targer aquiered, just kidding" and so on. But overall it was very hard to play and that was probably unintetional.
