Pixel-perfect collision detection should be working now. Since it's now possible to knock opponents around, please try out the attached binary (with friends if you've got 'em) and give feedback on initial move balance. Are some moves overpowered? Is it too hard to hit with others?

Three things to note real quick -

* the middle kick will be adjusted up or down 1 pixel - right now it's too hard to hit with since the foot goes into the opponent's belt

* blocking does nothing yet

* knocking players over rolls the screen : )
