Ty for the feedback, I'm probably going to make some minor changes that hopefully will help the readability. I think it's really hard to tutorialise orbital physics without a big expansive tutorial because the way it works is kind of just inherently unintuitive. If feels like you should just blast off in the direction of your destination but that just doesn't work at all!
I'm glad you liked the music, that was the one part that I didn't do! :')
