I love the concept of taking a walk while listening to a story about a (first-person) character walking around on a mission. I just have a feeling the story could've been a little bit more interwoven with the activity of walking around (in a certain area) or observing your surroundings. The fact that you constantly have to return to the app to start the next audio clip is also a big con, although I understand the choice considering you can find items on the map.
