Rated your game. I really liked the concept and the music was great! Here is mine: https://itch.io/jam/gmtk-2019/rate/461862
I recorded my backyard at night for the ambient sound of the game. I also played around with 2D audio depending on where the car was. I didn't have much time to really play with this, but I also lowered a low-pass filter on the car's engine as it moved farther away. Sound design is a lot of fun and I would like to focus more on it in the future.
