First I played the game, I didn't have any sound, I checked the comments, and figured out I need to play again.
I would've wanted to say that music would be a great tool to set the tone, but even that was well executed.
If you are looking for some constructive feedback, I think the interlude scenes could have some optional networking/talking scenes with the other survivals (think of Expedition 33 tent / base) to give the players an option to get to know the world, and build some connections towards the peer survivors.
I also have to say, this is the best paced game I've seen during the jam.
