I was trying to keep things brief because there are so many entries. I figured a sampling was the ideal way to communicate the swath of ideas without making the tracks overly long. Lengthening the songs from a compositional perspective should be pretty easy.
For the survival game I'm making, I'm planning to have a sound track that's something like 2-3 hours long, maybe longer so that it takes a while to get tired of the ambience.
I'm glad you're enticed to want to hear more! Thank you for listening. :)
