The attention to the audio really stands out, here. It raised the hairs on my neck toward the end.
I'd +1 the suggestions of giving feedback during repairs. The visual design didn't feel as polished as the audio, either. There were artifacts on the main window, and I missed seeing sparks and gas leaks. I'm curious if you could play with the scale of the "not star" more to turn up the cosmic horror element, too.
Great first submission and I'm looking forward to seeing more!
