Good stuff!

Hearing this on the NG Chat radio station Heavy Metal right now. It's awesome! Thanks for making and sharing it.

Would make a great final level song.

In my opinion that's some really good work. The synthie goes really good with the mood of the song, gives some dark melancholic feel to it. The only thing I would change slightly is the mixing - if you take the hi-hat out a bit more with heights, same for the crash - and the lead synthie slighty down, maybe just -0.3db or something. Try also panning the synthies in the back against each other so you have at parts changes in the pan, think that might give it a confusing effect and adds to the atmosphere, cheers!
