The core idea works surprisingly well. Game ended up being more difficult than I anticipated. I encountered some bugs though that seem easily reproducible. First is I can hold the planet off the far left side of the field and not all the way to the right, so the bounds of the planet hover don't seem aligned with the playing field. I also had the game crash on me, I think a planet went too far left when dropped and escaped the game field and then the game just never game me another planet. With some bug fixes there is a neat project here.
