your video is an example of a blind race.. where the people playing are completely unaware of what the level will entail
One of my favourite videogame videos is this blind race(o)
it is such a cool format.. some players create levels for others to race blind in teams of four, switching every death
it creates opportunity for so many great moments
i love how the level designers are there to comment, then afterward they race some of the hardest levels in mario maker(i)
your link is of one of the original hacks which was designed to be just totally brutal, but Mario maker has a more inviting difficulty curve
what's really fascinating is the history(o) of this subculture and how it was already fully formed long before mario maker
it almost feels like mario maker was released specifically for this group of super fans, or in response to them
it all started in the mid aughties when a person hacked a ROM so thae could make thaer own levels to torture thaer friends with
More and more people got exposed to this insane idea of hard, though beatable, mario as people kept passing around the hacked rom
the kaizo and puzzle communities are remarkable.. both in consistently high quality levels and the people are warm and welcoming
both kaizo and world record attempts at puzzles are exercises in optimisation
and the puzzles(o) feel like spaces for interacting with algorithms and data structures
