The game is really cool, and the mechanic of rotating around the boss makes the game much more interesting. Just to add, on mine there was a bug where the background was completely black for a few seconds.

davedalus was the code behind it but it uses centripetal force as the main mechanic like a planet circling a sun inputting an option just gives a small boost in that direction rebound just reverses your direction entirely. If we didn't do tap to move the game would just move to erratically so we restricted the movement to just tapping to make it more coherent
