Investigating My New Cursed House | Family Curse

This is a very weird game. From the 'enemies' to the story, right on to the ending. I enjoyed most of the puzzles, minus the final one. If you understand the solution, please let me know in the comments.

Family curse is a mystical horror from the first person with a frightening atmosphere. Immerse yourself in the intricate history of the Crouse family and find out the terrible secret of the people who died in the cursed house.
