Very well capture similar vibe as the FNAF games, so good job on that. Having the janitor as roaming "treath" was interesting as well. But I'm sure he was just doing their job.
1 feedback I would give is to maybe open/close cameras on click, when looking for the janitor in my room I accidentally kept hovering over it and it opened camera and it made me panic more :D.
Also some night indicator would have been good, for progress reasons, then it feels like you progress, instead of feeling like it's just a loop.
Great job.
