Contrary to the time listed in the video, he actually defeats Bowser in around 5 minutes and 5 seconds into gameplay. Still, nobody ever this game that fast before. In fact I believe the video is right in saying "World Record".
I guess this was done last month, this record is almost unbelievable. Throughout the video I never saw him () get his by a single enemy which begs the question "were cheats involved?". He came rather close to getting hit a couple times but made it from start to finish in a few seconds over five minutes. Unbelievable!
