It's OK....
I think this is OK for an 8-ball game, but I think you could've put an extra twist in there, like you type in any kind of question (not just yes or no) and it gives you a random fortune, kind of like a fortune cookie. But that's just me. Also, more choise of music would be nice. I mean, if you don't want to do that kind of stuff, I understand. But that's just what I think.
