While the video interview below is primarily focused on Let it Die, because Akira Yamaoka was for many years associated with Silent Hill (after adding his trademark sound to the series and acting as producer for Konami), we asked the Japanese developer about his thoughts on the cancellation of the whole Silent Hills project and its rather scary P.T. demo. Here's his brief, but to the point answer, which is in line with those of many other horror game creators:
"For P.T. I feel disappointed, it's unfortunate that it was about to get released but it pretty much got cancelled".
Here's the full interview with Yamaoka-san about Let it Die, music genres, and more.
