Sorry, I'm still here. I was gone over the weekend, so I didn't get much play time in. I do agree with the sound thing, if it all possible. The only other things that I can think of at this point:
1. It would be cool if you could earn extra points for clicking on various items when they pop up (at least the first time).
2. You should let users tweet, even if they didn't score anything. Personally, I'd get a kick out of seeing a tweet saying "I scored 0 points on..."
Thankfully I haven't had any "issues" with beta 2

I know it's still probably just a coincidence, but what an awful coincidence
