This was pretty good and I admit that the death scenes did manage to scare me (particularly the one involving "Spike") but several things were unexplained like why the house was the way it was, why is there a giant spider, the ghost of a girl, etc. Honestly, it just feels like the story is that the protagonist just made an incredibly unlucky choice in picking a house whose hauntings are not explained at all. If you want to have backstory in your haunted house game, take after Psionic3D. He makes games with haunted environments like this but with snippits of backstory strewed throughout the games just to give the player an idea of what's going on, what has happened, etc. Other than the lack of backstory, you did a great job doing and I hope to see another haunted house-type game from you someday.
