Fun little dodgeball simulator, probably designed to rob you of quarters, but still cool.

The game is not perfect, for example the players you don't control at the moment are way too vulnerable - you dodge the ball as one guy, and the one who stands behind him does nothing and gets knocked down easily.
Also, it becomes too grindy the further you progress - you don't stand a chance unless you protect your strongest player Kunio at all costs, always pass him the ball and either stunlock enemies close to the border by quick shots, or try to perfectly time the same strongest attack over and over. It took me insane amount of tries to actually beat the first loop on the factory settings, I would be in debts by now if I had to spend real money. 1CC/max difficulty seems impossible to me.

But despite that the game looks cool and is fun to play, even though I'm usually not into sports genre.
Loved that Japanese high school vibe and the references to the previous Kunio beat'em up game, too bad it was all scrapped from the worldwide release and turned into a generic sports sim.
