This is the first Donkey Kong Country 2 TAS ever. The movie aims for overall fastest completion and doesn't give a flying banana about bonus rooms. Warp barrels are used whenever possible, meaning a large part of almost every stage in the first two worlds is skipped.
The impressive thing about this movie is that the not-so-accurate hit detection in this game allows the player to squeeze through extremely small gaps - at blinding speed, of course.
