What video game on the computer is this?

Ok, so all i remember is that you character wakes up with amnesia in a strange creepy town.

And its like an escape game where you have to find objects that let you find other objects to get out.

And i remember that you had to play hid and go seek with these really creepy kids and they had a "secret weapon" that you had to find which i think was some dead girl you had to dig up..can someone help me?!What video game on the computer is this?
Sounds a little bit like "Harvester", but it wasn't a secret weapon, it was the way into a cult.
