Dolucky no Puzzle Tour '94

Certain blocks, gray in color, cannot be removed unless they're touching five colored blocks as they vanish: the goal is to quickly fire five blocks to remove these before they reach the player character at the bottom of the screen. There are also random power-ups that can be acquired. The blocks have facial expressions that change depending on the number of similar blocks they're touching, allowing the player to see how close they are to clearing them if the top of the screen cuts it off. Smiling or grinning suggests that there's three or four in contact.
