I don't really understand what's up with everything since it seems fairly basic things. Mainly a build (?) with a zombie and chat message events.
Unless the map is generated, given things sort of look the same everywhere. If that's the case, that's actually pretty cool.
What I do like is the death cam at the end.
But if you intend to make it scarier you should try to modify the way the monster attacks you, since that "unh" is not that scary.
