I think the concept is really clever, though I wish you could aim without clicking and you could readjust the ship even after it had been launched. The hit boxes on the planets could be slightly bigger to make the game more forgiving. 

Nice graphics but the game itself is not forgiving because you must start at the begining of the game

Cool idea, I like being able to set my trajectory to pre-fire at where I think the final planet will be to intersect. Fun and strategic.

Kind of wish I got to stay on the level I failed on though, hurts the motivation just a little.

Looks good as well, love watching the little planets spin around in their orbit! :)
