It's an interesting idea, and pretty atmospheric, but I'm not sure what to do other than run/drive around. I went into the 'oil rig' and found a green orb I couldn't interact with, I tried climbing the 'mountain' and hit a dark bubble I could get past, and I drove/swam/ran all the way to this Space Needle-looking tower and tried climbing it until the disc at the top stopped me. Never saw the ship in that one screenshot.
It's also a little frustrating not being able to move the camera with the mouse, and it makes climbing stuff weird sometimes.
