This game has some cool mechanics that was fun to explore. The music and audio in general was also pretty good. It has some humorous writing as well.
I know I said the main mechanic is cool, which it is, but it was also wildly frustrating/unintuitive for me as well. My main problem with this is that it is too hard to predict the path of the planet motion to have any meaningful pre-planned asteroid shooting. I would try to line up my asteroid in a place where I think the planet will cross on its path to try to push it, only to find out that the planet will not go there, so I would miss my shot entirely or do something I didn't want to. In the end it would devolve to something akin to me just trying to shoot the asteroid as near the planet as possible as fast as possible. I know this may have come from a place where you want to simulate real orbital physics, but sadly for me it doesn't always mean it translate to a fun game. If there was simply a line drawn showing the predicted path the planet would be going, then maybe this could be solved, but I'm not quite sure if you can do something like pre-calculate the physics interactions of the physics objects either.
