For some reason I can't fire the turret. So I end up losing a lot of the ship right off the bat. Seems like no one else is having this problem, but I can't see what the issue could be. Or is it supposed to be like this?
Edit: Figured it out. Duh! For others who also got stuck, you have to move the little dude/chic/whatever to the tile/terminal near the turret itself toward the front of the ship. Then press "E" to interact with it. Then you can mouse aim and fire.
