One of my other favorite games, its by 3  to 4 same or different colors it's similar to "Magic Jewelry"game. https://www.retrogames.cz/vyhledat.php?search=Magic+Jewelry&vyhledat.x=12&vyhledat.y=12

Playing field also feels a bit to wide. As in too many columns of blocks.

Love the update, but you should really add some rails on the left and right side to indicate the active playing field. I would just add a semi transparent black box on left and right side

It's pretty good.
