Perfect FPS Controls, and i mean Half-Life like perfect. The mounting felt a bit floaty but it's a demo, so things will get worked on anyway.
It just feels great to play, what's there is already very solid. It immediately reminded me a of a certain old game by the name of "Manhunt", could it be that it was a source of inspiration?
The way the Enemies fall or can get back up is pretty neat aswell.
Also very coherent and beautiful art-style, very talented devs and the full release will certainly be great.
