While I definitely find it clever that people can find these glitches/exploits...I personally find it more impressive to see how fast someone can beat the game the way it was intended to be played. My reaction to something like this is like seeing someone finish a 400m dash in a few seconds because he walked backwards due to some bylaw everyone forgot about. Smart for sure, but seeing how fast someone can get to 70 stars and get to the final boss draws my interest more.
That being said, this is still pretty crazy, you definitely need skill to pull this off.
