Now this is something I adore, aesthetically speaking. A first person view in a Resident Evil-esque setting with smooth camera controls is definitely very aesthetically pleasing and dour. I really do want to see where this goes next.
As a demo, it has a few issues - one is that, while the shoutout to RE with the door animation is appreciated, it gets a little old a little fast when it's every single door in such a small setting. Along with that, I am sure the ending is a sign of things to come, but it kind of takes a very, very sharp turn in tone from the otherwise somewhat subtler scares of the house itself, and resulted in more of a laugh than a spook.
Still, really hope to see The 3rd Night go somewhere.
