Often during the demo I could not see into my ship when I pressed space bar. Tried zooming in with middle mouse button but it would not allow me to see the inside of the ship. Moving did correct the problem but I got into situation where I had to get a crew member to put out a fire before I could move but was unable to do so due to the bug.
The last mission of the demo it was REALLY hard to see the engine to target it as the camera was constantly blocking ones view.
On the whole I did enjoy your concept so keep up the good work and improve as you are already doing.
