Error 4516 Demo Windows game

You work the night shift at a local office building, when strange things begin to happen. After working there for a while, you quickly come to the realization, you are not alone. You must walk around the desolate hallways, but be careful as one wrong turn could be your end.

The game consists of five levels, each offering something different from all the rest of the nights, making for a fun and ultimately scary experience. The game will be out sometime next year.
