THIS IS HILARIOUS XD
I found a little glitch. When Both opponents kill eachother with artillery, and both have cards that have 0 attack points, the game goes into a loop, in which it keeps skipping turns without an end.
I destroyed a planet with meteor showers, but instead of the bule guy dying, he's stuck inside what appears to be some sort of different world. And as he shoots out of this weird "box" if it comes back to hit him, it only increases the "box" by the size of the explosion, and I can't kill him!
