This is actually a fantastic game. It reminded me a lot of 'September 1999' an equally amazing horror game that sets out to do the same thing of proving that good art direction and tension are the only real things necessary to create an incredible experience. Is it worth a dollar? Hell yeah it is. It's short but it's definitely worth it.
The only real issues I found were with some confusing moments, not knowing what to do, and the AI not behaving the way normal zombies would by sometimes standing right next to a doorway and waiting for you to walk right into them. This is something that can probably be solved with NAV Proxy Links? Thought I'm sure the developer already knows this.
In any case, this was awesome. Thanks for making games!
