Do we have any evidence, though, that ChainChompBraden was exceptionally skilled and well-practiced going into this? Because to my understanding, the level ID for Trials of Death hasn't yet been made available, meaning Braden is the only one who was able to attempt this. Meanwhile, Tidal Wave was and has been available for literally anyone, and despite being the most prestigious level in a game where people pour tens of thousands of hours into beating near-impossible levels, it's only been beaten by two other people since it was verified last year, and these are the three best players in the game each with several tens of thousands of attempts on this level (they have god knows how many tens of thousands of hours of practice from other levels of similar but lesser difficulty).

Kaizo Mario can introduce some complexity that GD can't by having more than one type of input, but GD's hardest levels are so insanely precise (Mario Maker's 60 FPS or anything even near it would render top-level GD play essentially impossible) that even though these both push the limits of what humans can physically achieve, GD seems more difficult at its highest level of play.
