all other carnival games have a "back to carnival" link after you've played them, but balloon popping does not. it has a "back" link that returns you to the main balloon popping page, which itself has a link back to the carnival, but users are unlikely to take this route as once you've played, you don't have much reason to go back to the main page for another, what is it, 12 minutes?

this is on lines 3 and 4 of the Games section of usability and random improvement
