I remember playing this game a few years ago and it was absolutely fantastic.
However, that’s not the case anymore; just like as other people have stated there are a lot of ads (every time you click something you’ll receive an ad, which can take up to roughly one minute waiting in total).
Besides that, if you’d like to get a free trial for a new level then the ads don’t even work, which makes the game immensely frustrating.
With all of these accounts I’d give the current Dancing Line game a 2 out of five stars.
