Or, at least, they will be shortly. The patch that adds trophies hasn't gone live yet. It'll also come with a new difficulty setting that adjusts where you respawn and how your arm acts in certain situations. It sounds like it'll make the game a lot easier. The fixes and changes will also be coming to the Xbox Live Arcade version of the game.
A bit more detail on the changes and a comment contest can be found over at the official PlayStation Blog.
