The unreliable narrator is clearly the main attraction here, implemented in a way that is both clever and fun - exaggerating to seem more badass, and backing down when challenged, all of this affecting the gameplay in real time. Beyond its unique storytelling method, I never felt like it was doing anything terribly special, but it also doesn't really need to. The gameplay works fine as a vehicle for the story, but at times it does feel like a rail shooter due to obvious and unimaginative enemy placement.
