mechanics are completely and utterly broken.

- moon moves too fast and has too strong of an influence. The aiming line that supposedly shows the path of your projectile is misleading, since by the time the projectile gets there, it's out of date.

- moons speed makes it impossible to put anything in orbit, or slingshot around it (it just throws stuff out into space)

- already said many times, but you can just drive up to the other player and shoot them point blank

did you actually try playing it yourself before posting about it?
