This is an old video by John Wick, author of Legend of the Five Rings, 7th Sea and Houses of the Blooded (another cool example of an anti-D&D game, together with Greg Stolze's REIGN).
It’s a very unorthodox and interesting way of building a dungeon without any preparation but that requires a group of players willing to play its premise. It was created as an answer to a comment accusing of Wick of railroading his games.
On the "Complication Points" part, I'm still not sure if I'd use the 10-minutes windows as a mark. Does this window take in account only investigation part of the game? Or does the entire game session?
Maybe you could use Complications in another way: 1 Complication per player, at the start of the session, and 1 additional point every time the players derailed the game or bicker too much among themselves (like something I read in a post by Dave Arneson, where he said that he used random encounter when his game delayed to player’s passiveness).
Complication Points could work as a way to increase the tension on the table I guess.
The Bowl Dice could also have further uses, maybe by stealing something from the Hero Point rules.
