Interesting, but why?
I think the tetris was well programed, and I enjoyed the whole "its on grid paper" thing, but I am not sure about this random hand or the music from Family Guy. My recommendation is cut the family guy music and then work on the hand animation so that it draws each new block before it falls.
I'm giving this one a five, because though I think you made a good tetris game, we have good tetris games and the orginalality of yours, which might have bumped me up to a 7, seems to be half conceived or half birthed I don't know which.
