This walkthrough uses the original Windows game and its mouse interface. You remain in the office from 12 AM until the shift ends at 6 AM. The upper-right clock tells you how far you have progressed. At bottom left, Power left is the remaining electricity and Usage is the number of active power bars. The image shows the left half of the office with the DOOR and LIGHT buttons; move the pointer toward the other edge to pan to the right side.

This office screenshot was captured during a different shift at 3 AM. Its controls have the same labels you need on Night 1, but its 35% power figure is an example, not a target. Console and mobile versions use different input methods.
