The first thing you'll probably notice about the game is that it's not really traditional “Pong.” Because the AI never loses (the AI paddle "jumps" to wherever the ball is and then follows it), you get points just for keeping the ball in play, not for making the other paddle miss. This works, but I feel that never being able to beat the AI takes a lot of the fun out of the game. Sadly, there’s no two-player mode to let you play against a more realistic opponent. The second thing you'll notice (Larry Bucio even mentions it in the readme) is that if you get your paddle in a specific position (and it's not at all hard to do) the ball will bounce back and forth forever. As the readme mentions, moving your paddle a little bit will change this situation, but it happens often enough to be rather annoying. Also, combined with the above-mentioned scoring system, this bug lets you "cheat" and easily get as many points as you want.
