Great idea and nice execution! Art and music were good, and I enjoyed the difficulty curve of the levels (last one was pretty tough). One thought I had while playing was about the path indicator, which I at first thought was very handy, but it also led to me just pressing button's until my path was lined up with the goal rather than thinking about how to use the planets' gravity. Maybe reducing how far it shows might help this? (If you agree feel like that was not your intended experience.) Last thing I'd say is don't restart the music on a death. It's a nice tune and I'd love to hear all of it! Great work!
