As indicated in the game description: 5 endings total, with varying degree of 'happy'. A lot depends on your current relationship with Harcourt, how sane you are, and which location you went to during Chapter 2.
I tried different locations but I can't seem to get a different ending, is there more I have to do?
I'm writing up a walkthrough to help (should be out at the end of the month at the latest)
