A bit redundant, but catchy enough to survive as good background music. A nice dark ambience that screams for action around it, so I could definitely see this being sued for a game or something. The redundancy is helped by the ambient sounds and occasional switch-ups you do, and you thus make good use and get a lot of mileage witha fairly minimal number of instruments.
You've a lot of empty space there at the end, like almost half a minute of it. o3o It's a minor thing but hurts any loopability the song has (and also isn't really needed so it's possibly just taking up extra file space).
Yeah I know I got too lazy to cut it off at 3:30 am and just wanted an opinion on it haha
Please contact me if you would like to use this in a project. We can discuss the details.
