This topic was made a long time ago haha, I have the same problem. by the way is anyone even playing that game? Because I am and I have gotten pretty good .
It's this site called hockey.tk and you ust register an account and then just press play hockey and wait like 5 seconds until another screen pops up. Then you go into a room that isn't full (the begining room is for no stats and the training one is for stats) Then you press left click to pass and right click to shoot. By the way this game takes practice, some ppl are really good and yeah!
