While I love the idea behind this game the 'swiping' is very unresponsive. Very often when I swipe to the left or right it gets stuck or goes the opposite direction, leading to a very cool idea and very fun when it works, but otherwise an unfortunately frustrating experience.
Having had continued for a while now I understand why, it's not supposed to be a click and drag motion but rather a click, drag, and then click again on the appropriate side of the screen. I'm at least glad I got to figure that out and play the game, which is indeed fun when you realize your mistakes.
