I just want to say that, as a PhD student in astrophysics, this is the coolest thing ever. I'm seriously thinking about showing this to my students in class so they understand bound orbits and escape velocities, if you'd be ok with that!

Really, thank you very much for creating this game. I'm still freaking out about the game system. You are amazing!

@Kruskal Thanks! Yeah, of course I'd be ok with that. I'm happy it could be of use academically. The physics are cheated considering the scales I'm working with, but if it gets your point across then awesome!

@Calvoflash thanks! Glad you like it!
