Really good. I agree with LasviciousGork, it's a little empty, but that is good in some ways. It's perfect for a space game where you really need to focus, because it's a nice song, but you don't like get attacted to it and lose a little focus.
Definitely got more of a Castlevania feel from that than a spacey feel. The lead is fantastic when it gets rapidly paced. I only wish it had more behind it, it's a little empty as is. Like maybe halfway through the song, an actual drum set comes into play then maybe some different backing or lead instruments to flesh it out.
Thanks ill keep that in mind
