Zombies have had their colliders updated, which should make it so you can get past them now a bit easier. You can also see them in the dark by way of their glowing eyes.

Nice work!, thanks for letting me know. I have just played through and been able to beat the demo. I really like where this is going. It's got mega original Resident Evil vibes whilst being distinct enough that I don't immediately think of it as a clone. I find the atmosphere and glimpses of story are intriguing and I want to know more. At one point I did wonder around aimlessly for a while after I obtained the key card, I looped back to the control room but didn't go near enough to the PC to unlock it to make the progress, though I could see the path leading on from the lower right. I'd suggest making that a little more obvious or dropping a clue when trying to interact with the door.
