An interesting idea, i believe, but the result was not enjoyable, at all. The audio was jarring, and the sounds from the building appeared out of nowhere, with no directional sound. The gameplay was basically nonexistent because I see no objective, no incentive to do anything.
And I believe that last is the most important part, this feels like it was done in a very short amount of time, if you want to invest a little more time in this idea, you can give it an objective. Something to do, maybe look for something, or take things from one place to another.
