Due to some positive reviews I bought this game, but realized that it is not right for me. You have to paint with the finger lines, which then move its own momentum and with a little luck remove colored dots. Black dots may not be touched, however, they "devour" the painted line. Actually, that's a nice idea, how to use the touchpad playful, and the graphic implementation is appealing. Unfortunately, it is so difficult from about level 17, I've lost the desire and uninstall the whole again. In fact, I am also just happen to come so far, and from the beginning had no real plan. It would have been nice if you'd had to help sample solutions for each task, simply to the strategy to understand better and to train spatial awareness. So, however, the outcome was unpredictable and the gameplay is not very large.
