seemo has updates his Atari 2600 game”Flow. Changes:

Hi, here’s a major gameplay update : now you can move the cells of the matrix. Just hold FIRE and move the joystick, and the symbols on the row or column of the flashing indicator will move by one cell, according to the direction of the joystick. This makes the game more playable, and allows to clear cpu cells that weren’t clearable because of their position. ‘Blocked cells’ concept has been removed from the game. During game, you can select alternative sounds using the left difficulty switch. Scoring has been brought in the range 1-999, and level parameters have been tweaked, in an endless battle against ultra-high scores. – Simone
