I play all of these games and love them. But THIS one has a final puzzle that is beyond unreasonable. After hundreds of tries to get through it, I can't. Unless I buy gems and skip it, I'm going to have to move on to another game, which is pretty lame considering it's the very last puzzle. And for some reason, I rarely get the easy/hard option, it ls just always on hard mode by default. Developers, please, back off with such impossible puzzles!
