It's easy to create scrolling rooms like the ones used in Lucasarts games like Monkey Island (tm) and Day of the Tentacle.

To do this, just import a background scene that is larger than your game resolution. For example, in a 320x200 game, 500x200 is a good size for Lucasarts-type rooms.

That's all you have to do. Draw on the walkable areas, hotspots and so on, as normal, and then save the room. The screen will scroll to follow the main character around.

The script command SetViewport allows you to manually scroll the room around if you don't want it to follow the character.
