Super Hexagon is akin to "sight reading" or performing music "a prima vista", while DDR as played by most players is a type of rehearsed musical performance (or, well, dance, I suppose). Being able to play a prima vista is a rather specialized skill even among musicians; I've only known a handful of people who can do it really well. I don't think it has a ton of utility (at least I never found it to have a lot) and so it's not something that many people actively develop or train, though.
