Really cool song. I had actually never heard of it before, as it's an underground remix by Skrillex from his MySpace page in his early days as a producer.

The fact that in the entirety of the song, there are only 4 total "arrow blocks", is kind of sad. But, it is NOT an easy song at all. It is incredibly well mapped for being almost entirely directionless blocks. Would recommend if you want a super challenging map, though the heavy bomb and wall usage is not so fun. Trust me, you will want to turn on NoFail to practice, until you're confident that you can clear it without the "training wheels".
