The first level of the game involves Doc Brown riding his horse through the level in order to save Clara Clayton from going over the edge of the ravine on her runaway stagecoach. Whenever Doc Brown fails to reach her in time, she goes over the edge, and then a graphic of her tombstone appears on screen. The tombstone erroneously displays her date of death as "September 5, 1855", when it should've read "September 5, 1885", as in the movie.
