First person mode was a life saver. Much easier to navigate through the hoops. As for the missions where you have to destroy things, I would recommend having a third hand.
It's really hard using only keyboard and mouse, and my controller just would not configure correctly.
I think my setup was standard WASD + arrows, and I might have used the controller for additional functions as it was on my lap. I never got past these missions until the other day, I was psyched when I got through them. First person view was incredibly important though, I seemed to breeze through the ones that didn't involve attacking stuff.
