ok i figured it out! i was soft-locked. i had not found a blue key before going into that bedroom with the scary closet. so i was stuck in there forever Lol! there's no way to get the blue key when you are in there.
i figured it out because i just played the whole game again (loved it!) and i got the same objective for the blue key and this time i was not in the bedroom, stuck.
i wish i could describe it better, sorry.
anyways i loved the atmosphere. in this game :)
