Watch the video. In all mario games there is a timer, either at the bottom or the top of the screen, that when it reaches zero you're "dead" and must start the stage over. Watch the video...and you'll notice that timer doesn't go down constantly, like it should, decrement one every second. After he hits a full run, it begins to go down every 4 or 5 seconds. Its not normal, whatever it is.
