So the first thing I want to say is I loved the soundtrack. The music slowly growing more intense the closer you got to a monster was really nice. I also loved the approach to the house, where the trees' shadows slowly grew longer as you got closer to the house, it set the mood really well. I was a bit surprised when the sky went black, but then lightened a bit as I finally got there. There are two things I'd love to see done to this game, a major one and a minor one.

Major Thing: Is too big. I played for almost half an hour, and was only at three bags. A smaller mansion with fewer bags to collect, or even the same amount, but still a smaller mansion, would have made for a better experience. 

Minor Thing: I became convinced I was a millipede standing on tip-toe. That is to say, you hear like ten footsteps a second. These are not human feets beneath me. I didn't actually mind, because it was hilarious, but it did kind of kill the horror mood.

P.S. The game says 9 bags, but on the death screen I got 3/10. So there's a typo there somewhere.
