This was so weird, but in a good way. It was like listening to the thoughts of my past self, so in some sense a very interesting interpretation of the theme. I think it is intriguing as a concept, although not so much of a game because it lacks a clear objective or motivation for the player.
It could be a very interesting experiment if this was all taking place in a realtime room which a handful of people could join and 'leave imprints of themselves', which could then be spoken to. Might make for a unique icebreaker/conversation exercise.
