atari2600land has updated his single and two player simultaneous play variant of a very well known russian block game. The game was previously known as “Tetris”.

Release notes:

I got bored, so I added a little demo sequence that comes on after all the letters fall into place on the title screen. To exit the demo and return back to the title screen, press fire.
