FNAF 1 bug (or intentional...trick?)

[MikeTheLab]

On night 3, I ran out of power at 5am. Freddy's song played all the way through and as I sat in the dark, waiting for my impending doom, 6am struck! I got so happy and relieved for like, half a second, because Freddy STILL jumpscared me! at 6AM! :P

(It counted as a win tho, and I'd play night 4. Hence my question, bug? or feature? ;D)

Sidenote: I absolutely love this game! Great job Scott and Steel Wool :)
