Purrfect Match is a great game. Only trouble is that once I finish it, my browser freezes. Happened with Big Paw Pong, too. Play as long as you like, as long as you don't complete a game successfully. I'm running Opera 7.11 under Windows 98. Only thing to do is the three-finger salute, End Task, and fire up again. I think I won't test any more games for a while.
