The choice to put a password "save" hurts the enjoyment of the GBA version more than Majesco may realize; without any way to save the game's data, players don't have set scores to shoot for, nor can they stop in the middle of a puzzle session on the road.
It's one of the most derivative games I've ever played. You name a puzzle game where the object is to eliminate shapes, colors or other forms by selective grouping and you are guaranteed to find some element of that game in Super Collapse II...Not to say that Super Collapse II is a bad game.
