So, I wanted to do something special in honor of being selected for the PAX 10. So as a special addition to the game for the PAX build I have added a head-to-head competitive multiplayer mode for the show floor. I think it will be a lot of fun! After folks have warmed up a bit and learned how to play a little of the game, they can play against each other on a few special head-to-head levels. And maybe if people like the mode a lot, I'll figure out a good way to include it in the final game as well.
