5 Nights with BanBan

You have five nights to get through, playing as a kindergarten teacher in a place inhabited by the Banban and his monster friends.
You have an ordinary phone at your disposal, on which you can view cameras, read messages and answer calls.
Be very attentive and keep your eyes open to prevent the Monsters from catching you. Monsters don't doze off, but he's very afraid of bright flashes. Banban likes to scare the caregivers by calling them on the phone.
Can you make it through five nights?
