Okay this was a heckin blast, the game does a good job in exactly what it promises--physics based snowball madness. I just loved setting up a bunch of enemies after a ball or two and then shooting one seemingly missing wizard ball, then after a brief moment of uncertainty, the power kicks in and the board is all but wiped after some ricochet insanity.
Good job! Had an occasional minor bug with the arena view button showing the arena but being zoomed in like the snowball view.
