Yeah, you pretty much got the two "jumped" moments: the first stabby dude that just charges at you with no warning and the hallway of terror.

I get the impression that the window at the very start of the game that lets you see all the stabby dudes was meant as an introduction to the enemy, but I didn't see it that way when first playing. I had gotten the impression they were like scientists watching over an experiment. It might help if you made it clearer that they are not friendly, such as by making them act like they're trying to stab you through the glass, it would help that set piece convey the meaning better. As for the first actual enemy, I would make sure the player has access to the weapon before they encounter the enemy. It makes it clearer to the player that what they're encountering is dangerous, as the weapon announces that there are things to attack and things that will attack you.

As for the hallway of terror, My first reaction playing was to run backwards out the way I came. I never noticed a hallway because I hadn't even made it that far into the area before I started to be chased. Fixing this problem is trickier, but cutting off the path back and making the escape hallway more obvious might help.
