It's not easy, and if you mess up... you have to start over.
Tetris represents a guy trying to build a relationship. But it get's harder the further up he goes, messing up along the way. Thus, he has to start over to try and build the love.
Just an idea I had while playing the game. I said...heeeey xD
*also, I've had some complaints about the shapes being inaccurate. Yes I see that, but the reason for it is simple. I didnt think this would be noticed (like some other contests I've entered). Nor did I think I even had a chance, so I just did what was best for me. Sorry for the confusion.
