I love the voice acting! It's like I'm at a friend's house and he's backseat gaming.
I appreciate the little breaks that happen from time to time. I guess those are level breaks but the game doesn't make a big deal about them, just gives you a chance to rest your fingers. And that's all you need.
The score wasn't showing for me... I was going to comment that I would have liked there to be a score, or some kind of progress marker, but then I saw the score in the screenshots, so I don't even know.
