I don't even run this game and I can tell you that not taking damage or getting stuck on corners will be faster.

Likewise, don't know the game, so there could be something I'm missing.

But I counted about 4 slow downs, where DK is clearly losing its max velocity. One of them was because you got stuck on a wall for a second.

Other than that, nothing really stands out to me, but since I never played there is a lot of nuance missing there.
