Sounds used:

BGM: GD menu loop
Open app: Play level sound
Close app: Quit level sound
Wake from sleep mode: Crash sound


Reasons why I colored things the way I did:

App icons, page switching arrows, close button, and top screen button guides: GD default block
Folder icons: Windows
Folder inside: Menus in GD
Start button and bottom screen corner buttons: GD menu buttons
Cursor: Color of selected objects in the editor


The crash sound plays when you wake the console from sleep mode because it sometimes plays when you focus the GD window (or at least it used to, I don't know if it still does in 2.2.)
