Well done.  The game looks great and plays great, and the idea is interesting.  I really like the addition of the asteroids.

I do think there needs to be some indication when a puzzle is complete.  The first few levels I solved, and thought there was something left to do because I could still play and there was no ding or sign that the level was complete except the fade out - which I misinterpreted as failure.

That's really all I can think to criticize, and it's a bit nitpicky.

I also wanted to do something with constellations but I couldn't make it work mechanically and eventually scrapped that idea.  I'm glad to see someone figured it out.

Great job.

Nice job, overall. The asteroids look great, in particular. 

That long, rotating asteroid belt kept me waiting though, sitting on one of the stars until it passed by, for what felt like an awful long time. 

Also, the pause once you clear a stage is a little odd. Maybe some visual or audio feedback to let you know that you've cleared the stage while you wait for the fade-out would be a nice addition?

In general though, a solid constellation-themed puzzler!

this idea is soooo cool!!!! i love the art and the cool game mechanics/gameplay!

i think your game is broken. the drawn lines kept disappearing and the one time i did manage to close a shape the next level went black. am i missing something in the game play?
