This is a nice peice of work!
I enjoyed playing it, I found it when I looked up two player games, beacuse, my brother wanted to play a game with me. And as I was reading reviews I notices some pepole dont know how to play it, so heres some quick help for you pepole that dont know.
First, you must have two players.
second, one player moves with arrow keys and the second uses good old a,w,s,d.
third, the first player ( the one who uses arrow keys ) must press space bar to shoot, it will shoot the second player ( dont wory he dosent loose lives!; ) so you would want to get the ball in between the two players. Then FIRE!
I hope this will help those pepole that dont know how to play.
And over all, this would be a 100000000000/100000000000! But it only goes up to ten...
See ya!
