I like the green cloud idea thingy.
Although if you plan on using light effects for the green clouds, not everyone would be able to see it because of Graal not supporting many video cards or whatever.
BUUUT...the problem with NPC's x and y thing needs to be fixed first when loading into different levels. Take the train for instance, it looks awfully laggy because the player has to take the time to load the level, THEN the train loads the x and y a little off-center.
