Alright - I finally have replenished my old collection of Sierra adventure games, and I just got to work on the world's first Graphical adventure. And I'm stuck... already... like right at the beginning.

This may seem incredibly stupid, but how the heck do you cross the bridge to the castle? I try walking across, I look all lined up, and then I fall in the water. Nothing I type while standing next to the bridge works. Any help? Is this version faulty?
