Alone in the Backrooms

You woke up in a strange place where the walls are covered with yellow wallpaper and the floor is lined with a smelly brown carpet. You only have a camera in your hands.
Your main task: find 10 keys to open the door and choose the exit, but be on your guard, there is a monster wandering nearby, eager to find its victim.
Will you be able to get out? If not, I don't envy your fate...
