Ask HN: Looking for runtime programming / timer travel debugging video?

[NiceWayToDoIT]

I am looking an author who few year back made a demo of small video game where he edited code in runtime. And all was working on the spot, please can anyone tell me who is author, as in search I get overwhelming number of result but non is the one I am looking. I think originally he made it more as art concept to think about.

Notch does live updates when he codes. https://m.youtube.com/watch?v=Vi7WnVTLzHw is one example, but there was a more famous one where he was live-coding during Ludum Dare in 2011.

Thank you but this is not the one. The one I am looking was from some Conference, in front of audience, and it was 2D platform, developer (whom name I am looking really) was showing how he can change trajectory of game character in middle of jump. (not even sure anymore was it javascript or some other language)

I know it was something long before React/Redux had actions to go back or Quokka in VSCode.
