Audio instructions are an interesting idea! I think it would be nice to make them louder and add subtitles to go along with them for accessibility. There's many features of the controls, so they could be split into separate audio parts (For example, first it tells you how to get out of the pod. Once you do that, it explains how to orient in space and so on.) Tutorial is often difficult to get right, but I think it is very important for new players.
