I have a new game and have a question about level design

I do have a story but not a script.
This leads to another question I have about story delivery.
Being a independent developer with little capital, I was pondering different ways to convey the story outside of the AAA fashion.
I saw that Brothers a Tale of Two Sons was able to invoke emotion with a made up language. It would be nice to do something similar.
Most likely, I’ll be voicing most of the characters, a la abridged series guys on youtube.
