[PC][2005-2010]Point and click horror-ish game about twin sisters(?)

The game is one of those casual point and click 2D games, like Alawar or Nevosoft do. I believe it was more horror leaning, everything was dark and gloomy. If I recall correctly game starts with main character being nanny driving to the house she is babysitting in. Something blocks the entrance and that is a tutorial I believe. I also think the kids were 2 sisters and they were like the ring or F.E.A.R. type of dark scary girls. I think they escape and MC follows them to the house basement or something like that. That's all I can remember
