Thanks for playing! As I mentioned in that other comment, if you want to play the other character/levels before the bugfix is in, you can open up the opponent selection screen by pressing semicolon. The bug is just that that screen doesn't show up when it's supposed to, so by manually pulling up the menu and going through that, you should be able to experience the rest of the game as intended. And we'll be sure to let people know when the bugfix is up.
