Can you beat the impossible mode? It's the hardest mode in the game where all the lights are off, the only light is the flashlight. Marny moves faster than you and always knows where you are at, so even if you hide she would just wait there and once you come out of the hiding spot she would kill you. Beating the impossible requires you to know the exact locations of objects and find a way to not let her catch you. I as the developer have not beaten the impossible mode yet. Become the first one to beat it and unlock the super rare Golden Survivor achievement.
Good luck and be the first one!
