Pretty neat concept! As the other comments have also mentioned, the controls weren't very convenient. It would be a lot better if you could control the camera with the mouse like most first person games, which would also allow you to look up and down. I also think the game needs to be a bit more clear, for example I do not know where the reactor room is supposed to be so I did not manage to progress after turning the valve. Good job though, I am sure it would be great with a bit more polish!
