Wow, we had the same idea for the game mechanic! We even used the same flying sound :D I liked how you animated the background. More information on the planets would be nice, so that the player can calculate risks and not just navigate by random.
Hahahaha dude thats so cool! I'll be sure to check out your entry as well as soon as I get the chance, looks waaaaaay more complex and well crafted than mine!
Also, the door sound was too cool not to be used for the engines :D
