The entire video was not very long, only around four minutes, and that was because it contained plenty of slow-motion footage.
As for its content, it was supposedly a tutorial on high-level techniques, but in reality, it was merely a simple demonstration. To put it bluntly, it was an idealized combo string.
Link's aerial back-A combined with an aerial looping combo using Remote Bombs, along with flashy pursuit combos that combined his boomerang, bow, and Remote Bombs.
In an actual match, unless the opportunity was exceptionally good, aerial looping combos like that were basically impossible to pull off.
As for skill-combination combos, they looked incredibly flashy to players right now, but after studying them for a while, players would realize that they were not actually that difficult.
Moreover, in Super Smash Bros., jabs—that is, ordinary Normal Attacks—could be canceled with special moves to eliminate recovery frames and create seamless transitions.
But for most players right now, the finer points were clearly beyond them. They all had only one thought: this was nothing like the Super Smash Bros. they played!
What surprised players even more was Link's approach in the video.
For most players who had only recently started playing Super Smash Bros., once a fight began, they would basically choose to battle in the center of the stage.
Unless they were knocked out of the middle, they avoided the edges whenever possible, because the game was designed so that being launched beyond the screen meant death.
Likewise, if they fell below a cliff and failed to recover, they would also be judged defeated.
Therefore, only the very center of the Arena gave players a sense of security.
Because of this, combined with the percentage-meter mechanic, a match of Super Smash Bros. generally lasted four or five minutes, or even longer.
