Braid-creator Jonathan Blow on making the 'biggest puzzle game ever'

For ten years, Jonathan Blow has been working with a small team on what he believes is "the biggest puzzle game ever made".
The American developer is renowned as one of the fathers of the modern indie game movement, creating the genre-defining puzzle-platformer Braid in 2008.
Now, a decade on from his last project, The Witness, The Order of the Sinking Star is due to be released on Thursday - a game with roughly 1,500 puzzles that he estimates could take around 500 hours to complete.
