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’ve tried to add music. You can switch it on and off with the left difficulty switch. There is a little problem, though. When a block hits bottom, the note changes from what it’s supposed to be to a random note. I don’t know what I’m doing wrong, so any help would be greatly appreciated.
