I have never given a 5 star review before, because there is always room for improvement.
there are a few things to be fixed on this one, but it is honestly so freakin' good that I just HAVE TO give it 5.
so, this is a super fun and addicting game. I love the different modes, they are all so fun an engaging.
there is no penalty for losing, you just restart the level. the ads really aren't that bad compared to other games. (there is also a "remove ads for money" option, although I haven't purchased it yet) there is a 5 sec pop up in between every few games. they REALLY arent that bad.
the backgrounds cycle every level and every time you open Scale , and they are BEAUTIFUL and relaxing.
the only thing I would say to the developers, is that having a diagonal (right angle) piece would be cool. it could be a special move, or a regular piece. or maybe having 2 pieces at the bottom of the screen to choose from to use... I duno just some thoughts.
FANTASTICALLY FUN. bravo.
