I don't think horizontal block moving will make the game easier in the slightest. On the contrary, it could make it harder. Yeah, there are now more options, but with those options comes the burden of needing extra time to assess and Meteos is a game that does not give you time to react. If they make the game forgiving all of a sudden, yeah, it'll be easier, but if they keep the lack of time aspect the same, it shouldn't be easier at all.
