@flockaroo a friend of mine made a game a few years ago, a top down shooter in space (something like asteroids) but with accurate gravity. he showed it to a lecturer to brag, and now he's working on the final touches of their shared article about categorizing orbit evolution in the 2d version of the three body problem, with the same codebase from that game.
basically what i'm trying to say is, don't underestimate what you did here, it's genuinely impressive. lots of people would be interested in either your code or your expertise if you can make something like this for fun :)
