Well this was simple fun. :) Not much for sports overall, but a game like this seems to addict anyway... maybe it's my rebellious side kicking in. :) Even without the power ups it would be a fun time-killer, and I like the added gamble with the mystery box, though in the longrun you can't really lose with it if you just take a few at the start to either build up a score or go so low it's better to just start over. The upgrades add a lot of re playability though, and the leaderboards are good motivation. Nice work!
