Really impressed by the demo, this is quite a solid mix of old school FPS like Quake, Half Life and Unreal with a little bit of that weird sense of humor from series like MDK. And by looking at the video previews, there's quite a lot more from enemy variety, levels and weapons, which I cannot wait to play!
I have some feedback for things I didn't particulary liked tho:
1) It is a bit annoying to see objects cutting your FOV in half from the bottom when you grab and carry them around. Dunno if it is possible to make them not completely attached to the player's face.
2) The sprint-slide kick is a lot inconsistent when it comes to stun damage.
3) There are still some fall in framerate when you save the game or when it loads a new area.
4)The pistol shield being unlimited when in higher difficulties is a bit weird, I was expecting it to disappear from intense enemy fire or by time.
Overall, this is a great promising demo and I can't wait for the final game!
