The Witness is an amazing game. I highly recommend it. I’m glad he didn’t give away too much in his presentation.
I didn’t know of Brian Moriarty’s connection to Jonathon Blow and the Witness either. I was very impressed by that presentation. I remember playing Trinity when I was in high school, and feeling very moved by the full experience of the game when I finished it. It’s still in my top 5 for text adventure games. Now I want to replay it to see how it seems to me today.
The presentation also made be want to give Braid a second chance. I started it a while ago, but stopped after a while, I can’t remember why now.
