They were playing a new game though. I really wouldn't look at the invitational as an example of high level play where most if not all mistakes are punished.
It really looked like no one knew what they were doing since they seemed to be new to the game. I'm assuming they only had a short amount of time if any with the game prior to getting on stage.
Or it could be because it's a brand-new game and nobody really knows how to play aside from the 30 or so minutes that they (probably) had with it.
Lets hope so!
