This is an interesting yet terrifying concept. The audios and visuals were really well done. I feel there could be a bit more visual guidance on the expectation on how to escape: I only found the RAZR after a few retries; I expected something to be inside the actual buildings but there wasn't anything that could help me.
I only found one way of escaping, not sure if there are more, as I've looked around for a bit and haven't found much. I'm interested to know the intended escape routes.
Overall, this is definitely a foundation for a cool game.
