> The hack was originally discovered by NerdyNinetales on TikTok, and I was able to get it working on my own copy of the game.

He literally says it was not found by him in the linked video. He credits it to Dan Berr:

There’s a new quest that has fairly interesting characters. I think it shows up with a distress beacon or something. I followed it and found it interesting, although one part probably needs to be changed some because of how tedious it is.

I feel this is cheating some, because they use portals to move the camera. Impressive nonetheless, but nit exactly “without moving camera”.
