Welcome back to Jimmy Noodlearm's Pizza! Hover over Jimmy's head and click the arrow to reboot his system (more instructions in game.) Press E to close the power door in front of you, and A and D to move back and forth between cameras. Click the "Power" panel to open a monitor and replenish your limited power supply! If Lila the Pig crawls through your vent, make sure your mouse isn't hovering over her!
Thanks to Scott Cawthon for creating the original Five Nights at Freddy's and inspiring me to start creating video games.
