Wow, two in one day! This one is for (so far) my most anticipated game of the year. What you see here is actually fairly different from my original idea, which put more focus on the constellations. I couldn't find a layout that looked right, until I eventually stumbled upon the idea of having the spaceship-planet-thing as the focus. The Cloud and Rock Mario constellations survived the change, but the other two didn't really fit; however, you can still see them if you look at the background.
Thanks for your helpful critique, Seth.
