That would mean severe audio distortion, as said by this YouTube commenter:

As a computer programmer, I disagree, Elliott Belardo.
First off, if he reduced the playback speed (which would be quite a simple thing to do, if he utilized Cheat Engine), He would have to use software to heavily modify the sound playback, because when you change the playback of a game with CE, it messes up the sound. He would need to use pretty sophisticated software to modify the sound to be "normal" playback rate, without making it sound high-pitched like Alvin and the Chipmunks.
Next, if he really did reduce the playback, it would DRASTICALLY increase the amount of gameplay time required to actually hit 633 Seconds (If you can't do math, thats about 10 and a half minutes.)
If he reduced the speed by 50%, he would have been recording this for 21 Minutes...
25%, would have a 42 Minute recording time...
Accusing him of slowing down the playback of the game is ridiculous, due to the amount of work and energy required to make it seem legitimate, as well as the time involved.
Despite this, However, I cannot rule it out as a complete fake.
It's entirely possible that the person who produced this video wrote his own third-party software, which utilizes DLL injection to reverse engineer the game, and hijack the controls, using some basic AI and interpretation of the binary data being calculated throughout the game to remotely navigate throughout the maze. But the amount of time required to do this would be upwards of 30 or 40 hours, and the AI, if programmed correctly, would never die (Unless presented with an unsolvable scenario.) Plus, if the person who made this video has the technological capabilities to do this, I wonder what He's doing making videos to throw onto youtube, rather than going out there and programming the next Minecraft...?
Due to obvious reasons, I yet again have to rule that out...
The only other FEASIBLE (there are others I could invent, but which are even less likely... such as a Macro, blind luck, being God, finding a cheat built into it, Cheat Engine.... etc...) Possibility, would be that
This.

How about, in the future, instead of mindlessly attempting to rip other people apart out of sheer spite, or jealousy, we instead think twice about our actions, and be more civil-minded?

Plus, he had a previous highscore, this wasn't just a singular attempt.
