The concept is very fun, I took some time to understand it in the beginning, but I managed to understand it after a while.
It was an interesting concept, and I think this can even become a full game, (But I think I'd switch the sport to football, just because it's more popular).
Unfortunately I lost 7x1 and as a Brazilian, that is very painful.
Also I found a bug that when you resstart, the score remains.
Overall, very good and fun game.
