Horror Hotel is a short game about being haunted by a spirit of a man. You go around collecting keys to make your escape. You feel as though something is going to happen, but nothing ever does. And then you leave.

The issues you will encounter are; bouncing off objects and z-fighting. (objects fighting for the same Vector3 on z)

That aside, this is a solid concept. And I want to see what you'll come up with. Good job!
