The game is quite satisfying, the planets getting launched after getting hit by the moon was quite nice.
I do think perhaps the moon can just spin automatically? Cause I just ended up holding the right arrow key to make it spin continuously. The screen is unfortunately chopped off. Full screen works it isn't centered as well. I'm not sure if there is any audio but I couldn't hear any.
Other then that I think the game is quite fun. Am I a heretic for believing in Heliocentrism haha?
