Tower of Blocks

In Tower of Blocks, you have pieces falling from the sky that resemble Tetris pieces. However, the pieces can fall into place only if you guide them in carefully using the arrow keys. Otherwise, they can topple over, land on the wrong side, or land propped up against other pieces in a haphazard fashion. You can build the pieces up as high as you want, but you cannot let any of the pieces fall off the green platform or you lose! Also keep in mind that you are trying to build to a certain point before time runs out. This may very well be the new Tetris!
