When it all went bad - Cool glitches and space ship sound design.
First steps + the carnival - Nice use of theremin, vocals, and whistling. Great storytelling through footstep sounds, night ambience, and music fades. A highlight for me was when the footsteps became a part of the music at 0:55.
This is a creative piece that blurs the line between soundtrack and SFX, which makes it somewhat difficult for me to rate in the context of the jam criteria and other submissions. The SFX design is great, but something that would be really cool that I thought of from listening to your soundtrack is if the diegetic music faded into a bigger arrangement of nondiegetic music (kinda like scource or transdiegetic music). Just an idea!
