use the arrows to move your player. pick up balls with spacebar and then throw with spacebar. Try to knock your opponent out. Win by 2 rounds to proceed through the levels. This is based on a game I played once in the arcades a long time ago. Feel free to report any bugs or give suggestions, I'll tweak the game this week to make it better.
I plan on getting music loops for the start of rounds and for winning/losing to make it feel more arcadey.
I've only spent about 24 hrs on this game so far. My time was cut short because of the AFL grand final on the weekend, plus I had the deadline for the gamestudios.com competition. keep checking back for updates :)
