I pretty much use it exclusively, can't stand anything else. I have windows for games and ubuntu for testing stuff, I'll try the updated version.
Update:
Works great! Well done man. One thing I would change is the label "enemy" to "CPU". Pong doesn't really warrant the term "enemy" for your opposition, unless it's Pong of War (which would be smelly boots right? ha)
Do you recognise when the world won't stop for you? Or when the days don't care what you've got to do? When the weight's too tough to lift up, what do you? Don't let them choose for you, that's on you.
