I am very new to Unity and have been looking into using Unity for 2D games. This is probably a silly question but I have not been able to find any similar examples. I am interested in creating a small point-and-click adventure game, probably only a few different screens the player can navigate. However, all of the tutorials and examples I have seen are make use of a single screen, such as the 2D game development walkthrough (http://unity3d.com/learn/tutorials/modules/beginner/2d/2d-overview) or are platformers that scroll as players move through the scene.
I was wondering what the best way to handle multiple screens in an adventure game would be. Should each separate screen be a different scene, or is there a better way to handle this? Will the use of separate scenes possibly cause poor performance when moving, say, through a door and loading the scene for the new room.
