~45 minutes of DDR. The most annoying thing about the back arrow not working isn't that I don't get credit for the back steps -- it's that it mucks up all my combo scores! Having a 50+ combo and moving like crazy to hold on for Just! One! More! is one of the coolest aspects of the game! But of course there's no way to do that when every fifth or sixth step doesn't register whether you hit it or not. Le sigh!
