Scratch

So, I'm extremely new to Scratch. I go to the Art Institute of Indianapolis and my major is Web Design. So in one of my classes, Program Logic, we've began to use Scratch. I posted my first game I've ever made on here, it's a very simple Adventure Time Pong game. Basically, you bounce the penguin around for as long as you can. But there are some glitches, or something wrong, that I haven't quite figured out yet. The score sometimes messes up and a couple other small things that you'll notice by playing it. We have to have this game finished for a project in class and I was wondering if by any chance someone could check out the game and give me some pointers. It'd be greatly appreciated! Thankyou!
