It's simple, short (which is good IMO) yet addictive, and I like the mix between synth and western-like sounds.
So interesting that when I heard it I considered for a moment adding an intermission scene in the Flash game I am working on to put your theme in; but it would be too much work (the whole game is about a whacky confrontation in space, but it's fast action)
However I'll definitely think about it for a future project!
