Sounds like a bug, where in the house were you?
Thanks for reporting, fixed bad colliders in the windows. BTW I added 'How to play' in the description:
"-How to play:
Follow the Ghost Meter sound and indicator to find cursed objects. Once you find a cursed object the green lights on the Ghost Metter will on, so press 'E' to collect the object. Listen carefully to the radio to more clues. (Subtitles are in English)"
