A nice take-off on the classic Tetris game that offers some challenging options.

Use the right and left arrow keys to move the blocks as they fall.
The up arrow key will rotate the block 90 degrees.
Hold the down arrow key to speed up the drop of the block.

If a row is completely filled with blocks it will be removed from the play area.

The goal is to remove enough rows of blocks to keep the play field from filling to the top.
