If you don't mind my asking, how did you implement the enhanced script? I attempted it with a test project, but nothing seemed to happen.
Well, I can't really tell what's going on in your project, but I know you need a character controller component on whatever the script is on (whatever you're trying to move). Check on that, check on your inputs, make a "Run" button in inputs. Also, if you mean the thing just isn't mouse-looking, that is true... enhanced walker script doesn't deal with mouse input.
