I made these three short demos of soundtrack music that I thought could work here...
I see what YC means in that many moments in-game don't feel like they need music - the ambience of the ship is rich enough. But maybe at some points (like when a new story beat happens), a little tune could fit well.
Anyway, here they are - hope people have a way of trying them out along with the game itself. :)
