I think that the fundamental problem with this piece is the lack of a solid atmosphere and depth. While it has a very basic structure with the intro setting a somewhat interesting sound despite being very stripped down, it also sounds as if you diluted the same few riffs for minutes and minutes, droning into an abyss of repetition that fails to deliver an engaging experience. It's not even about dissonance: it's lack of substance.
If you elaborated the track by adding more instruments, possibly rhythmic synths, textures and sounds that could have enhanced your storytelling, it might have been an interesting space ambiance. Repetition should be avoided if it can't sustain itself enough to be considered immersive, and it's a shame because I liked the "analog" feel of the track, but it sounds like an idea that needs further revision and polish.
