Tilt calibration? The apparent need to hold your device completely horizontal at times too greatly restricts when and where the game can be played. Tilt calibration for different sitting and playing angles is badly needed. As best I can tell, that lack of tilt calibration makes it impossible to play in bed. Great potential, but without tilt calibration the game has little appeal. Requesting refund.
Очень необычная и увлекательная головоломка!
