Puzzle game that I played once and now can't remember??!!?

I played this cool as puzzle game once, but now I can't remember what it was called! I do remember some facts though. The people had triangular prism shaped heads and had bodies that looked like blocks. It was quite hard. I remember that the main story was that you had to go into rooms and find video tapes to play on the T.V. in the main room. It was something about a mother not letting her daughter go out with her boyfriend. In the end you put all the video tapes in order and the story made sense. Please, PLEASE, PLEASE, If you have played this game answer my question!! I really want to play it. Thanks!
