For being only a short demo of what's to come. This was not too bad at all!
Solid story/premise to boot and the this demo has me really intrigued as to what this school is doing beyond it's ending. What seems like a simple security guard job quickly turns into what seems evil. Solid graphics, atmosphere, lighting as well. And the game ran well on my system.
Overall, this game seems quite promising so far! Made a video on it.
