atari2600land has updated his single and two player simultaneous play variant of a very well known Russian block game.

Release notes:

Bug fix for B mode. Also, I changed the way the block looks for being able to go down or not. This results in the block not flashing a lot when it sets into place. This also means that there’s less time to figure out if you want to move it or not. Let me know if there’s any bugs or it doesn’t work on a Harmony or anything else.
