good and scary game.
if you get stuck by the star puzzle:
first press/click the A symbol, press/click the B symbol, then press/click the symbols besides/in the middle of the star in reverse order than the first two symbols, then press/click the symbol on the bottom and then press/click inside the star. you can then leave the house through the window (click at it several times if it will not work the first try). look around, read the note, turn around and wait. if that does not work, look around and wait where no note is. you can read the report about the history of the house at the end of the credits, you will find the report at the start screen.
