I did it on first night already or second night I believe xD I don’t think there’s a limit to that and I don’t think it depends on night. It’s probably just that people don’t switch cams as often on lower levels but I was actually switching them like crazy bc I didn’t really know how to play FNAF so I thought I have to look at all cams all the time lol. If you just jump constantly between cameras you’ll 100% get golden freddy poster after few minutes. I initially noticed it because I was hunting all various posters and easter eggs so I was switching between cameras like crazy and at some point when I noticed golden freddy it reminded me that yeah there was something to it in original game wasn’t it? xD
I really like implementation of golden freddy in this game it’s imho on spot.
