Sanatorium

Your car mysteriously stopped right in front of the old abandoned mental hospital. This was the first time when our main character, a little girl named Catherine, saw a ghost girl, smiling at her right through the sanatorium window. Soon after she's realize in a dream that the girl was brutally murdered and that;s how we come to your task to help her out investigate and find out what lies behind the Catherine's nightmares. The first thing you need to take care of is to get through the old hospital's gates. Yet, for some strange reason, there's a cop watching over and he probably has the keys, but the problem is that you can't just nock him down that easily. Sanatorium is a typical point and click horror adventure in which you must unveil the secret of many deaths that took place inside the old building. Behind every step of yours there's a little puzzle you must solve first. The game has been released back in 2010, but we put it here since it's been used for 2d version of slender man.
