The Battery is a main mechanic in the game. It consists of 9 Bars, Then it will be draining slowly, The time in that it drains depends on how many doors the player is using and how long the doors are closed for.
Once the battery is empty, a power outage will occur. After a short time (the player has only about 10 seconds left at max.), Candy will enter the office, jumpscaring the player and ending the night by causing a Game Over.
If Blank breaks the window, he will break the equipment insided the office and cause a power outage regardless how much power the player had left.
There's a rare glitch, where Blank might break the window after the power has run out, leading to the player being randomly jumpscared either by Candy or Blank.
