Hi, I Remember Watching The Walkthrough Of A Certain Horror Game, But I Do Not Recall The Name. Can Someone Tell Me The Name?

The game was about a man wandering around a mansion, solving dark puzzles while he is chased by a killer holding a cursor shaped weapon. He eventually finds out that it was all a computer game, and the weapon was literally designed after the mouse cursor. There was then a bunch of trippy sequences, and the end credit shows how some of the death scenes were made via clay stop motions.
