It's a great buildup, you don't lose interest at all even though it's "quiet." This shows me that you have the potential to reach the top of the NG charts, and I hope to see you there someday.
Man I really enjoyed this! it reminded me a lot of Resident Evil/Silent Hill at the start! and gets more energetic, really liked this!
Could imagine walking through a seemingly deserted town on a dark cloudy day, only to be chased by zombies as the music gets more energetic to the end.
5/5 Keep it up!
Please contact me if you would like to use this in a project. We can discuss the details.
