"The Line" iOS game

My current iPod game obsession is "The Line" by Ketchapp, the company responsible from bringing the popular tile game 2048 to worldwide success. In The Line, the player has to guide a blue dot along a long path with many turns. The dot can be moved by sliding one's finger along a green area at the bottom of the screen. The goal is to avoid hitting the red walls with the dot, which ends the game. Along the dot's path, there are several "rivers" represented by thick blue lines, and the player must let go of the screen to get the dot over the river.

There are also small blinking squares along the way which can either make the dot smaller for ten seconds, allowing for more room to move the dot around, or give the dot the temporary ability to break through the walls. Another special bonus is the occasional x6 path, which increases the player's score by six points instead of just one when the dot is passed through it. The score increases continuously at a very fast pace until the game ends. My weakness is getting the dot around corners; no matter how much I try I keep hitting them. But I have gotten some pretty high scores in the game, although I have tons of room for improvement.
