I dunno about dark, this is just proper techno to me.
Minimal but still driven.
Nice high bass compressed kick in this, I do like the way these kind of kicks act on a soundsystem. Very deceptive.
I thought maybe the main riff, stab that runs all the way through could maybe have more motion, or drop in and out a bit more, as it`s the main mid high drive, but gets a little overused and loses impact.
Verall, some more stuff happening would be nice, some synth work, or more movement and ambience. Something to lift this up above being a mixing tool.

Good stuff though mango, it`s really nice to finally hear what you can do, and I`m pretty impressed with the overall quality.
