Wow, it's been some time, but I've seen some updates recently so I knew it's not dead. I don't even remember the previous demo after such a long time.
Technically there's nothing to complain about, so it's actually polished for something made from ground up.
It plays ok so far. Enemy stagger state really makes the combat for me, and it feeds nicely into both ranged and melee combat.
The level is too dark. Just when I got the last, red, keycard I managed to fall to my death (even if I knew what I was doing, I would try to jump down since I assumed you can't reach the way back out of the corridor - Half Life gave me some really bad habits).
From bugs, robots sometimes try to shoot you through walls and they hit the back face in the spot that would be the exit hole.
