My brother and I both love this song (in fact, the first thing Xaihyv said when he saw your PM level 2 video was "this music is awesome").
It's like Daft Punk, but more dynamic. I especially like the first bass, and the organ solo at 3:06.
On the whole the level iteslf reminds me of the CED Expediator from D3 (an incredible maze, as well as some very similar room and hallway designs). One room was especially fun because it reminded me of the place in the Expediator where there's a Spyhunter who, when you shoot him, says effectively "I won't shoot you if you don't shoot me, I'm on your side", but then starts shooting you because you had to shoot him to get him to talk. I nicknamed him SpyNutter :P.
5/5 10/10 for both the song and the level.
