I find it pretty hard, but on the challenging way (i try to collect puzzle and all kongs together instead of racing through game and come back take them). When you fail you don't feel cheated because the control are tight, so if got mistake, it's your fault, then the only solution is do it the old way: try again and again to memorize all the way and path.
But the real pain in the ass are time attacks (little too hard for me, seems will give up to get all gold medals) and the K level (fortunately they are generous on coin in these ones). For the last one i remember spend countless life and time to pass the 1-K but got a real blast with it.
But we must first concentrate ourselves on the way to entertain people, for video games to live. Else, it's a world where sales representative will win, which has as effect to kill creativity. I want to say to the creators all around the world:"Courage, Dare!". Shigeru Miyamoto.
