First of all, I love the ghost model - even though it's simple the cloth animation looks really good. Sound design is simple but works well. The variety of minigames makes the game much more fun. One time my camera did get stuck in one room whilst my ghost was in another. I would consider maybe adding some sort of visual indicator to show where the detective is, since I could be running off into another room to fin d haunted objects and I could easily lose his trail.
