I'm 99% sure this concept has been done before and technically the player does control the trajectory of the space ship so it doesnt really feel ike anything is out of control. I don't know if there was meant to be audio but when I played it there was none.

Thank you for your comment!
I did some search on the internet and found that most games related closely to gravity is that kind of platformer which we control the direction of gravity to walk on ceilings, with a few exceptions which we decide the initial velocity of our avatar in space to get to the destination. The cloest search result to my game is The Universal Sandbox, which is more like a simulator but not a game.
So if you do find a puzzle game with similar concept which the main mechanics is to directly control mass and size of celestial bodies to create gravitational influences, please let me know! I'll be very interested in different interpretations of a similar concept(that is actually part of the reason of why we are joining game jams).
About the audio, I confirm that currently the game has no music with it. Maybe I'll challenge myself and try to compose next time. For now, please pop up some light jazz and enjoy the game!
