Sorry for missing instructions, I just 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)"
You can't interact doors, and can't run until the end of the game.
