placed all the stones on a lit up fireplace, counted the clock-strokes, tried it on the lock... nothing. what im supposed to do?

Hello, I beat this game earlier today and unclogged the toilet. Will there be a new game+ mode for us experienced gamers who wish to have an extra challenge? Thank you, Reginald Pursebody

I had try many ways and times on shower, but still no unlocked. Also if I not turn on the flashlight, the bathroom is complete dark. The brightness settings also no effect.
