Dustin, I was excited for this to come out but I seem to lack the coordination to figure it out. What's wrong with me? I died 20 times in a row in 5 minutes not being able to figure out how to get up the walls consistently. Another day I tried again, same thing. I gave up. Feel like a doofus with the other comments saying how easy it is :-( .
How about having the game make a sound if someone challenges you. You are often in the room with everybody already in a game or busy, so naturally you open another window in your browser and do something else - need a noise to know you've been challenged!
