How does multiplayer work?
I can't tell if this game is competitive or not. As near as I can tell, we just keep going until the time runs out or one of us dies and then the highest scorer wins.

I was reading on the dev's website that doing combos creates obstacles for the other player, but I can't find a more detailed explaination of how this mechanic works. Does anyone know?
