Interesting idea with the footstep sounds denoting gameplay, and I liked the ironic narration, although a bit more background and/or obstacle sounds might have been nice.
However, in game terms this defaults to boppit, indeed when I first played I assumed I'd have to tap the d key to run quickly, and then jump and slide in an arcade action way.
