A simple demonstration of how to make pause screens and suspend gameplay which works best for the application_surface drawing method found in GameMaker: Studio 1.3+.
Shows a "clean" background-only look, a "gameplay snapshot" look, plus a method where you save the application_surface to a sprite and then draw the sprite instead - all of them without leaving the current game room. Also shows how you can spawn pause overlay objects to handle unpausing or other menu actions.
In-game buttons for navigating between rooms (useful for mobile demoing). Extra line to the documentation to point out the need for 1.4.1577+.
