I just read this in a game review on the front page: "Blaze takes you through 45 different candle-adorned 3D objects [...] This is done by way of touch controls — one finger to twist, two fingers to rotate — just like Zen Bound or, in the case of the iPhone 4, using the integrated gyroscope if you choose." I didn't know that. Or am I reading it wrong? Does Zen Bound 1 or 2 have gyro controls?
Zen Bound 2 uses the gyro for improved rope direction control. The difference is subtle, but you're likely to appreciate it when playing in a moving car. If you shake the device sideways but keep it in the same orientation, accelerometer causes the rope to sway around. Gyro devices maintain the correct rope direction despite sideways acceleration. In other words, Zen Bound 2 on 4th gen devices is noticeably better when turning corners
