I love that you dove into the minds of three separate characters! Taking the theme to a new level! 8 tracks for the jam is something to be proud of as well.
Outside of some repetitive structure in the tracks, which I've seen others mention, I'd recommend taking a closer look at your mix! The bass kind of swallows some of the other instruments at times.
"Bitter Cold" is one I gravitate towards naturally (my entire submission was based on the cold lol), but "Alone and Adrift" I think has the most potential of all of them, given some more dynamics and a couple extra parts thrown in there!
Overall, really nice submission. Nice work!
