Ty for the feedback .It's quite hard to get a contrast with such a limited colour palette but I'm making some changes that I think should make the text more contrasty/readable.
Sorry you had trouble with the game. I'm trying to think of some ways to make the tutorial a little better, but its quite hard without throwing lots more text at you. It's just inherently a difficult thing to explain because orbital physics are very unintuitive.
I'm glad you liked the music, as its the part that I didn't do myself! The person who made it is very talented :')
