Tetris (in the making)

So I was just experimenting how I'd execute the Tetris pieces and the background on Flash and I exported what I had and converted it to a .gif which distorted the quality of the animation (although now it really does look old school, doesn't it?)
There is a start button that flashes at the beginning that I may or may not make interactive so viewers could click start to play. Other than that, I've realized I need to make the stage of the animation longer or make the Tetris pieces smaller to fit all of Google.
