All you have to do is to start a cooperative game with only yourself and put both your hands over the two sets of dual wiggle-sticks so each palm acts like it's own control stick. so when you play the game you have more time.
However this does take a small amount of getting used to.
And your wrists ache like living hell if you don't try moving the controllers around.
I completed most challenges with a high rating by doing this.
Also by doing this you can remove two of the more difficult cousins in the collect all cousins challenge.
And other stuff.
(has this been said before?)
I remember trying this once and I didn't have much luck with it, but good job finding a new method. Wow, so you could get rid of both cousins hiding behind that tree.
Good find!
That's interesting and oddly enough, I never thought to try that. :lol I'll have to bust out WLK and give it a shot.
