'because making ONE game in the game jam is too easy, let's make lots of them!' :). Like the idea, but the collision detection for triggering converations was frustratingly poor, and the audio often started several seconds after the conversation had gone past - if Unity, you need to pre-load your audio. Since its linear you could probably put it all into a single big audio clip and just use sub-clips to load the next section, would make it respond instantly.
