this demo doesn't seem to do that? There's no stalker enemy you have to avoid, like Nemesis from RE3 or the Alien from Isolation.
The man that comes up to you and attacks you seems scripted, in that he appears to grab you regardless of what room you're in after a certain amount of time has passed. He's never seen walking around the halls and therefore you don't even have to hide from him. He gets you no matter what eventually, from what I've seen (I could be wrong - the playthroughs appear to vary randomly each time, and he might have just not appeared in these particular ones). If you're going to omit hiding mechanics, then you have to at least have combat to make up for it. But this demo doesn't have that either. No hide-and-seek, no combat - what is the point then?
This is probably just a really bad demo that doesn't reflect what the actual game will be like. I'm reading that the actual game will have combat, and if so, they should have really included that somehow in this demo. At the moment it just feels like a waking simulator without any hiding or combat gameplay.
