On the last stage of Aries, you spend some shots clearing out the small red area in the center instead of clearing the large red section on the left. Why not take out the red and white sections immediately and drop the constellation?
It seems like manipulation of stars will be a big part of the gameplay. How frequent/hard to manipulate are they? For example, at this point you only have yellow balls supporting the constellation:
If you could get another star, then the level would end right there. Of course, "starring" your way through every level would be rather dull, but it seems likely it'd be faster than taking all those segments out one by one.
Right here, you're spending a star on red:
Wouldn't it be better to use it on orange or purple instead? The star does basically the same thing that a normal red ball would do.
In general, I suspect even if the gameplay is optimal, you won't be able to convince people it is unless you can describe exactly how the RNG works. "I fiddled with it until I got a result that seemed good" doesn't seem to fly very well these days, especially when by your own admission you occasionally have to spend shots to no purpose. :\
Edit: however, there's clearly some potential for solutions that come out of left field. I found several of the levels to be entertaining; if you can do more levels in a way that doesn't involve just clearing out layer by layer until the last supports are exposed, I think you'll have a solid movie on your hands.
