Why Is This Chord Progression So Unsettling? (Need Technical Help)

Hi everyone,

So I was listening to an unused song from the game Tomodachi Life, titled 'Failure'. This piano piece has a lot of dissonance, for sure, but I'm not sure what makes it so unsettling. Is anybody skilled in counterpoint to help me understand why this is the case? Unfortunately, there is no score, so perfect pitch might be helpful. I'd love to figure this out to incorporate in my own compositions!

Almost every chord is a polychord of the one of the essential aspects of a major triad (root/third) and an augmented triad, generally voiced so that the relationship between the major and augmented triad results in some sort of tritone. The little high piano licks are all based on embedded tritones too.
