I love the way the bass kinda thrums through the entire song; it adds an almost electric feel to the song, and it never gets in the way of the other sounds. Mega props to your mixing skills my friend. I'm not sure how i feel about the speed up in the last third of the song, but the pieces individually go together really well and i didn't feel like it took away from the song so that might just be a preference thing. I do think the slowdown at the end works beautifully though. I'm not really sure where I'd see this in a video game (aside from maybe a DDRE track) but I would be neither surprised nor disappointed if it were in a game i was playing. The ending I think would have been way better if you'd let that last note ring out instead of cutting it off, but as it is now it actually loops pretty well so I wouldn't call that a problem so much as, again, a preference. Keep it up!
