Wait for notice to pass. When you start the game, click F for flashlight, and hover your cursor over the top part of the window to close the shades. Even though this is just an office showcase, someone else is lurking on the map..
Office is bound to change a bit, but should be mostly finalized by now, you'll probably see some differences when I drop the beta I hate the fact that I still haven't finished fnaf restored lore, so I'm basically remaking it but with a new style. Hopefully I keep my promise and make Five Shifts At Freds 2.
