Clever but unfortunately I don't think there was much reason to go up or down. Also I don't know if I'm just being an airhead but I couldn't find a way to backspace which meant that if I made a typo I couldn't save myself. Good work though!!
The reason to move up or back would be if you played hard mode, since in that mode cop cars would come at you from the sides, and unfortunately there is no backspace lol, although hitting enter would clear your text if you made a typo.
