I got stuck at the tutorial, even though I could see the air escaping, I couldn't "find" it for the tutorial to advance.
There was a floating white arrow, but I assume it was for the next objective, because it was behind a door I couldn't open yet.
edit: ok, I didn't realize that I could force open the other doors (duh), and opening the side door allowed me to get to the arrow and find the actual breach. The animation of the air escaping "up" from the central room was misleading. Maybe have it escaping left, indicating that it's leaking out the left hand side of the ship?
