I didn't know you added sound for trucks rolling by in World 2. I don't mean to be rude but this sound fx is so loud it overpowers the music, which i can no longer hum along to.
I know it is meant to sound like a vehicle moving past but in all honesty it just sounds like static noise corrupting the precious music, imo it needs to be removed entirely. The horns are cool though, just too loud.
Also i have to say that all the sound fx in general are a bit too loud. I would be happy to remaster them all against a music track in order to get the balance perfect. Give me a shout when you come online retro as i need some specific info on the raw files.
