Yeah, I had a similar experience when I played this. I agree with a lot of your criticism. I've certainly enjoyed the game for what it was, but it really needs a rewrite. The story definitely feels like it was supposed to be much larger, but then it was stitched together last minute to meet the deadline. Still, there are flaws in this story that don't have anything to do with that, for example:

It's revealed that five years ago, the protagonist's mom was murdered, but the protagonist didn't know about it, because his dad told him they divorced and are separated now. The 28 years old protagonist doesn't know that, despite still living with his parents. I find that much more unbelievable than the actual supernatural stuff in this game.
