It's a TAS of the most beautiful Donkey Kong Country game on SNES. This run uses warp barrels.
It improves the previous run by a little more than 4 minutes.
This is a tool-assisted speedrun, made on an emulator, using frame-by-frame shooting, savestates, and rerecords to overcome reaction time and human error. As such, it is purely a form of entertainment, and is not designed to show skill.
