Finally I finished your game.
After getting a key to the basement by going upstairs and finding a key in the laundry room I took it and unlocked the panting the one in the same room as that smiling painting then I went to the basement door the one where when you get text that says this is locked when you don't have the key went down there I got a hammer where I then I had to smash one of the painting's when I found and destroyed the right one I got a cross that's all I'm going to say.
