I thought this game was impossible to play the first time I tried it. Yet, for whatever reason, I felt compelled to play it again the next day, and the day after that, and now I just love it for its challenge and simplicity. I wouldn't think arrow key controls would work well for a game like this, but they do, because the collision detection is rather forgiving and the gameplay just takes a bit of getting used to. Hexagon has made me realize some games don't need a gradual difficulty curve to have a learning curve.
