Both Creative and Difficult
I love this game! Why? Because for someone like me, this can improve their hand-eye coordination and reflexes! It is also as challenging, if not more, than Flappy Bird. I have had no crashes or restarts so far. It just slows down a bit when the Game Center welcome pops up, as with any other game for Mac.
