Perhaps it's the poor jumpy touch "contol." Perhaps it's the horribly inaccurate tilt control. Perhaps it's the fact that I had to read the instructions about 3 times to figure out that you basically have to cover all sides of the square in order to score. I wasn't able to find this out myself, because it seemed that game felt it necessary to randomly decide to give me a game over, without warning."
