Dissonance can be a good way to make your listeners uncomfortable, but doing it with more and progressively louder synths for half the track...all the way to the end, no less,would not have been my choice. Try resolving the dissonance sooner, but without coming back to your "home" chord, for instance. Or even start a different chord progression with an off-site in each one.

I can understand the idea you were going for, but by the end it felt like you were beating a dead horse.
