Hey Nev,I love this idea... especially for the runner. Since he is much faster, the player needs to view more in order to control the player better. I will keep this in mind for later. But definitely a very good idea.
Have you thought about the possibility of a zoom? This game almost cries out to be able to zoom in and out smoothly according to what u do, like smooth out when you run/walk, and zoom in when u interact with things.
