I like hearing how you use BIAB to explore possibilities in your creations.
The music is well constructed and certainly has a sense of drama.
My only criticism is that it doesn't quite capture the "now-or-never"-ness of the situation you are intending it to be. In my view it doesn't build up the tension enough. I'm not getting a picture in my head of two astronauts running out of time.
Just my two pennies worth ...
