Not sure if it's something I'm doing wrong, but in the single player game no matter what level I select (I have tried both small and medium lv's) the space backdrop is always the same, even though the lv's talk about nebula's and other unique things the only thing that appears different is the planets/placements/sun type. It's like all the lv's are in the bright/cloudy looking backdrop that you see in the "advanced interface" tutorial.
