Thanks for the comments guys.
I wonder if I'm going from the north to the south or the other way around.
At first, I was thinking that perhaps you should have made it so that the player goes either up or down, rather than from left to right. However, perhaps you meant to leave this ambiguous? Is this why the player goes from left to right?
Indeed, the orientation was chosen to be ambiguous.
@captain catton:That's cool that you've been to the bridge. Did you ever live in Korea, or was the trip during a visit? It's true that North and South Korea both accept defectors, but defecting isn't always a simple process, and doesn't negate the fact that the countries have never signed a peace treaty and are separated by the most heavily fortified military border in the world--and that consequently there's no getting across Freedom Bridge, and no way for most Koreans to ever see their family members on the other side of it.
@Theta, @Animator:Thanks for the kind and encouraging words.
