I think it really depends on how the randomization goes.
I'd not necessarily call it a "game" yet (there isn't any real challenge), but I think it can be expanded upon pretty easily. Good work!
Bug: You can move the dark matter into the spaceship part, and push the ship around. Don't worry, I ignored that in my rating :).
Noticed no one has left a comment. I thought i'd give you some encouragement since you can't see the ratings. Know that this is my second favorite of the 11 I've tried. That's pretty good!
I did, still didn't let me drag it. What I'm saying is I either didn't know how to play or it didn't work once built.
I couldn't drag the earth where it seems to show it should go, so I can't bring myself to rate it very well, sorry man.
Biggest issue was with the controls, but I also didn't understand what you were supposed to do. I liked what I saw though.
