I like this game a lot, i don't know about you guys. When I'm bored of BB and I it's raining outside I usually come here to play. It's a flash game where you need to do wasd or arrow keys to move and x/spacebar to kick.
hax actually has organized leagues too, i'm a founder and commissioner of one (Hax Basketball Association) if any would like to check it out come here.
(If you come to an HBA room my name will be James Harden btw)
