Thanks for playing! The audio was a last minute consideration so I didnt put much thought into it but I tried to still make it fit a bit. Also the physics stuff in the game is actually quite simple and mostly repetitive as I just had to repeat for each object. For example, the gravity code is an extension which only consists of the code below 
and for each combination of large planets to smaller planets, shown below, I just had to write the names of the planets and a gravity speed which I defaulted to 100.
