Different from what I am used to hearing out of your fine works.
The dubstep feel to a video game was just what newgrounds really needed from the git-go.
I cant put my finger on what game you pulled your main source from, but it sounds extremely familiar...something leaning in the N64 direction so to speak.
Flawless piece, no clipping, volume control in the beginning could use a bit of fine tuning ranging from 0:30 - 0:54, where as the the power behind the electronic "kick" over powers the melody just a smidge.
Other then that, after listening to the loop a few times, I find myself in a trance. Great job :D
