The general gameplay concept is pretty good, although I think that the hit-scan is a little too tight. I'm not personally very good at first person shooters, so it might be a skill issue, but there were a lot of times where it felt like I clicked on it, and nothing happened (this may also be because of how large the crosshair is with no clear indication of the center point. I was unable to find the last thing in the 5th house, but I enjoyed this, and the gameplay could definitely be expanded upon.
