On a list of things you could do to make Super Smash Bros Melee harder to master this is certainly one of them! I would put attempting to play this game with a keyboard (via Dolphin emulator) about as hard as going through Dark Souls with a Guitar Hero controller!

As Heeeww's video points out, not everything is harder. Advanced competition skills like wave dashing are easy to pull off, but what good is it if you can't attack your opponent without dying?! He puts up a good effort, but something tells me he'll be switching back to controller soon enough.
