A Link to the Past also had a see the sky technique.... When you're on the pyramid you also see the sky in the background. Also worth noting that the only sprite on screen, where Link is outside the Library, is Link himself. All the environment at that point is tiles. Then when you pick up the sign post for example, it replaces the ground tile and the sign post becomes a sprite link is carrying. Great video by the way.
I've watched the whole vídeo. But really don't know how a green background with a yellowish inverted 4 in the center became part of a RPG town. Art is something different hahahaha
