I can't wait for the full version, I mean hunting down all the agility points and secret orbs is fun. But it will be even funner when it actually saves the ones you find.
I think the demo was a bit easy and I hope they make it harder. Because wiping out all the Los Muertas in an hour would be weak.
But everything does progress faster in the demo, so I have extremely high hopes that this game will kick complete ass at launch.
