This game WAS nice to play with, addictive, but design is now totally different.
Now, gems are smaller, much less distinguishable from each other, turning a nice to play game in an hard to play game...
If and only if previous design is back, then I will play again with it (note: I own an iPad 3, I wouldnt even imagine tiny new gems on an iPhone, even on a 5!)
