The Additional Properties tab in the Level Parameters Window contains a property list used for editing a variety of level properties that determine things such as which directions the level may scroll in, weather the player's inventory is carried over to the next level, and how far off screen various objects may be while still being kept track of by the game engine. Each property in the list is described below. (For more information on using property lists, see Common Production Tasks.)
