I think my games glitched, every time on the 6th night, Freddy's stuck standing on the right door and never moved away, forcing me to just keep that door shut the entire time, but the power keeps running out when I do that.
If it helps, I'm only playing the browser one so far, I haven't downloaded the game itself...
I'll give you all an update to see if maybe the issue is only on browser gameplay.
Edit: Nope, still had the same issues...
