I happened to stumble upon this game a couple of days ago while searching for games to play at school. I got it on my USB drive to play with me and my friend during lunch hour. He amazed by the game! The server was easy to create and always seems to beat me as an alien even though I practiced it before him. I copied it onto his USB and he gave the game to his friends and other people and we had a blast. We got a good amount of people of a class of about 20 to play and they also became interested in the game. (Because he knows so many people, I get the games and he gives it to other people). We even managed to get a whole class playing a game occasionally!
Pretty fun game and even better with lots of people!
