Dancing Line - FUN

My sister came to me this morning with a new game on her phone called Dancing Line. At first I said something like "meh, I've seen that kind of gameplay before". But I always give a try to every game so I did the same with this. 20 minutes later, I felt lost in this game. It's unique, fresh, good physics and free.
Here is the link. Enjoy
