Five years after I first played it, Blow has let go and The Witness is out. There are now got 600+ puzzles and the world has been remodelled inch by inch. And this is the first time I’ve seen it since then. So how does the game live up to the goals of 2011’s Blow? And was it worth the extra $5.2 million he’s spent on it since then…? (Warning: contains mild spoilers).
