I wasn't aware of this game until AFTER I saw the movie. Made a lot more sense after that. Watching a guy solve the same puzzle over and over felt like an odd narrative choice.

A labyrinthine Shinjuku would still be way cooler. Shibuya station doesn't have quite the same disorienting featureless repetition to it, but offers a more overwhelming MC Escher-like experience where you can often SEE exactly where you want to go in the near-distance, but every path and every turn brings you into a completely different space, and rarely any closer to your destination.
